Ok this morning my wow worked just fine. now when i try to run it this pops up idk why or how to fix it. i tryed looking on forums for fix but everything i tryed just dosent help. I also have another wow i tryed running molten on that one same thing happens. If anyone had similar prob or knows how to fix pls tell me in comments. so i tryed running as admin i deleted data interface wtf folders i disabled my antivirus firewall etc.. and it still pops that thing.

Redownload the game (minimal pref. to check it out faster). If it works, replace files to your original one.
If it does not, make sure your firewall / antivirus are not blocking data stream (meaning, missing files download) from Blizzard.
