Lajex Profile Page

I played a character up to level 10. But after logging out and trying to log in, the game gives an error. I deleted the folder with the contents and extracted it from the .rar file again. After this procedure, by clicking on the WoW.exe file I was able to log in again. However, when logging out and logging back in again, the same thing happens. I'm not going to do the same procedure every time I want to play. This private server is useless.
