What's interesting is that I went to that bit.ly url mentioned and it goes to the Tweaking.com All In One repair tool, which techs actually use to repair computers... that is odd indeed. So then I looked at the toms-world.org link, do you use something called Restore Point Creator? Or were you using some kind of system repair tool at the time that might have called it?

It looks legit, but I'm not going to download it to find out
The error also looks like a legitimate .NET Framework program crashed, and the author of Restore Point Creator software caught the exception and gave people a way to report the error back to him.
