I keep getting an unhandled exception error and client crash. This seems to primarily happen when I am switching from one character to another and randomly started occurring earlier this week. I tried to do a clean install, that didn't work. I tried all of the steps in this thread:

https://www.reddit.com/r/pathofdiablo/comments/2zziuu/d2_errors_guide_to_fixing_crashes/

I can't do the last step because the guide in the drop box is no longer working it seems. The only way I can switch characters without crashing on my next attempt to join a game is to completely log out to the main screen and re-enter my password. If anyone has anything else I can do to fix this, I would appreciate it because, while the game is playable, this is super annoying.
