AI errors are VERY difficult to track and even harder to find - even with log files
Considering this is a single case basis, I'm assuming either something went wrong during install, or there was an attempt to change files - otherwise the report would be widespread.
The AI is rediculously sensitive and will crash from everything from a missing line to an extra space or comma.
I would suggest to the OP that he reinstall and make sure there are no files changed.
If that doesn't work he can post his logfiles for scar and ai
