AppHangB1 problem

Greetings.

Yesterday afternoon I started having this problem, possibly after a non-critical client update. What happened is that the Wow client started freezing, and also jamming my Pc until I reboot it. Googled this, and seemingly people have been having related issues, but I found no solution.

If I use the Launcher, it opens up, and immediately freezes.
If I launch with Wow.exe, I get to log in, choose a character but it then locks up when the loading screen bar is 80-90% complete.

I have disabled all addons, deleted wow.exe and launcher.exe and ran the Repair tool, to no avail.

I did not install or change any other software yesterday either. First Wow worked fine, then it did not any more, and the last time I launched it after the client had frozen for the first time during game play there was a "installing non-critical updates" message.

Here is the error report:

Ended up uninstalling the game, deleting everything, and reinstalling.

Works fine now, but it must have been something wrong with the game client as I didnt change anything else, and Im using copies of my old addon and Wtf folders.
