Make sure your Cache folder is in your folder when running Icecold Launcher. For instance, when you run launcher than you get an error. Go to login screen for game using WoW.Exe than you will see you have Cache, than if you use launcher than you see Cache folder is gone after running it, than getting an error. It means that there is a problem with your patch. My patch automatically made me 4.3.2 somehow. Post a SS of you opening WoW Launcher with it open. Or just check top right hand corner of launcher to check what patch it is. I hope this helps. If it ionfact DOES say 4.3.2 just download Utorrent than get the patch for 4.0.6a from website link on Icecold Home page. Hope this helped at all :P
