A couple of weeks ago my installation of GAIM stopped working, with a Visual C++ runtime error. I logged a lot of hours solving this problem, prompting me to create a new page just for reporting when I lose lots of time due to computer issues. It's in the Flattland Related pages to the right. Read all about the problem here.
Ugh. Well, at least I did a bunch of other cleanup on my computer that didn't cause it to completely fail!
