I think today's patch was mostly to change the login interface, since from tomorrow everyone will need a battle.net account to log in the game.
Anyway, Cypher, it didn't work for me.
Got an error like:
"Can't find the procedure entry point RemoveVectoredExceptionHandler on library KERNEL32.dll"
I think it might be the old "Windows 2000" OS instaled on this computer at my work.
Gonna try it later on my home.
