Solved Problem with Loader

Hello, I have one problem. When i start game all is normal (connecting to battlenet, log in) but when i try to start second d2 i cant log-in with another hero. (Heroes is difference its not same) . I see this error i dont know why

 

You will probably need to back up important files (mh configs for example), uninstall D2 completele, then reinstall it. I had the same issue, only when joining / creating games, and reinstalling solved it (thx to Gix).

 

Thank you ! Problem Solved !
