A couple of days ago I tried to log in and play Diablo III. However, the launcher got stuck in Initializing... Then I got the message "Failed to download required file. Check your internet connection". My internet connection is working perfectly. I tried changing it to run the program as Administrator, nothing. Turned off my firewall and my anti-virus, nothing. Still gets stuck and getting the same message. I ultimately uninstalled the program, as many treads in the forum said to do, but when I tried to install it again, it got stuck on Initializing and 0.0%, and afterwards I get the same message. I've read many treads saying to delete the Update folder and the Battle.net folder, as well as the .tfil and .mfil files, nothing.
Does anybody know how to fix this problem?
P.S. I got the same issue while trying to install SC2.
I also tried to install it in another computer, same issue.
