I've been using Chrome for a while now, and suddenly today it won't work anymore, but only on my User account.

Whenever I try to open Chrome I just get the "Aw snap" message saying that "something went wrong." This message appears no matter which page I try to go to. Once or twice I did manage to get these product forums to work, and once I got Facebook to work, but that's all.

I also repeatedly get told that I don't have permission to use "Google Chrome Helper" or "Google Chrome Helper EH." I clicked on "Always allow," but I still have the messages pop up every 15 seconds or so.

Strangely enough, I tried using another User account on the computer, and Chrome works just fine on that account, but not mine.

I tried removing Chrome and reinstalling it, and I also tried creating a new user profile, but neither of those things helped.
