TortoiseHg crashes when trying to open preferences in file menu

When I try to open an option in the file menu, I get the following failure:

#!python

TortoiseHg won't close if I just click OK, but I can't access my settings.

The only thing I did was reinstall TortoiseHg (updated to latest 4.2). I experimented a bit yesterday and when I put my old Mercurial.ini file under C: / Users // and tried to reopen Tortoise it completely crashes and won't even let me open the program at all. Once I delete the file, I can open the turtle, but not the access settings.

I'm not sure what might be causing this problem. Does anyone know what I can do to fix this problem?

Edit: Tried re-installing again but still seems to be a problem. I noticed that my old repos are still listed when I delete. Is there a temporary directory where they are stored that I can delete?
