Before you ask, yes I've checked other threads, to see if there is a fix to my problem, and no, none of them helped.
Here what I've tried so far
Deleted the config files
Deleted Logs
Deleted Errors
Deleted Cache files
Downloaded a custom launcher
Waited to see if it was a connection error due to my internet connection (it wasen't)
Launched the program with both 36 bit and 64 bit
Made a new account to see, if it was because of a ban or something (again, it wasen't)
Please help me, I'm getting sick that ugly "connecting" and "Battle.net" box... please help me
