Can't run the game? Look here!
Problem #1: Launcher doesn't start or error messages occur
- Most likely, you don't have Microsoft Net Framework 3.5 or higher. You can download it here
- We also recommend you check whether your antivirus did not damage game files. Delete it or add game folder to exclusions and reinstall the client.
- Please read carefully the following guide and add game folder to windows defender exclusions.
- If nothing helps, you will be able to run the game from main.exe, the only thing that will not work is window minimizing.
Problem #2: Play button doesn't activate
You need to download the latest update patcher and extract it to the game folder, replacing all required files.
Problem #3: Mix.bmd file not found
- Most likely, you have extracted the latest update patcher into the wrong folder and trying to run the game from there.
- Make sure you are running play.exe or main.exe from the full game folder.
Problem #4: Install the latest graphics card driver
Just update your graphics card driver to the latest version. If that doesn't help, turn off antialiasing in the launcher settings.
Problem #5: Game client crashes after selecting character
- You need to update your graphics card driver to the latest version.
- Also, you can try running the game without launcher, but straight with main.exe file, then it should work.
Problem #6: No more characters can be created
- Your characters are displayed on the website, but can't see them in the game.
- It means, that you have typed your account using the wrong letter case. For example, I receive the following message, when I enter "Bel4enak" instead of "bel4enak". Those are two different accounts.
- Letter case in your account is saved when you enter the game for the first time and create a character.
- For example, when entered the game for the first time, I typed my account as "Bel4enak" and created a character there. that means from now on I will need to always type "bel4enak" when entering my account.
- If you forgot which letters in your account are lowercase or uppercase.
