1. Multiple Instances Error

Process Already Running
Your Account Is Already Logged In To Another Computer
Unexpected Error With Login Session

These are the error messages you will get if it is a multiple instances error. This error occurs if your League of Legends account is already logged in on another computer or another version of League of Legends is running in the background.

Riot is quite specific about your account, so you have to make sure that you only log in from your computer. Otherwise, you will no longer be able to log in anywhere. This is one of the common errors that occurs to players and is quickly resolved; just follow the instructions below.

The easiest way is to restart your computer. In case you had two versions of the League of Legends client running in the background, this will both shut down, and you will be able to log in to the real client.

If you are not sure if another version of the client is running in the background, open the Task Manager on your computer (Ctrl + Shift + Esc), find the open version of League of Legends, and press “End Task.” In case you forgot to log out of your account on another computer, change your password so that you can re-enter the League of Legends client.

2. Patch Update Error

League of Legends Error Code 002

If you have been playing League of Legends for a long time, then you know that updates happen from time to time. Riot has released new updates, and you can’t play until your game is updated.

Well, sometimes, during the update, it can happen that some file is lost or it is installed incorrectly, which means that the whole update was installed incorrectly on your computer, which will prevent it from logging in to the client. When solving this problem, we can’t just restart the computer, and we need to analyze the problem a little more to understand what actually happened.

What you can do is turn off your Firewall; it can sometimes block some update files because it finds them potentially dangerous and thus complicates the update process. In addition, you can check your Internet connection, maybe at some point, the Internet connection was interrupted, so some files were not installed.

There may be a problem with your computer’s memory, in which case you can try to clear the space on the Hard Drive or SSD. If none of this works, try Repair Client, and you always have the option to reinstall League of Legends.

3. Account Banned

Riot Games makes every effort to prevent trolls and rude players from harassing other players and takes seriously the reports that each player receives. For example, if your account is reported enough times for hate speech, insulting other players, or intentionally helping an opposing team, Riot will ban it.

The ban can last temporarily, depending on the reason why you are banned, and you can also get a permanent ban, in which case you will no longer be able to log into your League of Legends account.

4. Account Suspended

With a banned account, your account can be suspended, also for a definite or indefinite period of time if there is a suspicion that you have cheating software installed on your computer, you will also find yourself in a situation where you will not be able to log in to your League of Legends account.

Sometimes this is a mistake, so in both cases, you can contact the Riot Games Support Page, where you will try to prove that your account was accidentally banned or suspended with evidence such as screenshots or statements of your teammates.

Be careful; only with a reasonable explanation and quality evidence can Riot Games remove the ban from your account; otherwise, you will not be able to access your account.

5. PC Software Issues

Error: 0xc0000005
League of Legends Error 1B
Unknown direct x Error
The program can’t start because d3dx9_43.dll is missing from your computer.

What is almost the most important item when gaming is quality gaming equipment. Quality gaming equipment means that you will not experience problems related to graphics, lags, and more.

Also, if your drivers are out of date or your OS is also out of date, be prepared for problems when logging in to your League of Legends account. That’s why you need to follow updates on your computer so that you don’t have to solve this common problem.

If you still get some of these error codes that indicate a problem with your PC’s software, try updating your Windows or your Drivers. Compatible Drivers can be found on the GPU’s website, and you can download them manually.

You can also try to repair your League of Legends client or try to open League of Legends as Administrator, and if none of this fixes your problem try reinstalling League of Legends completely.
