Requesting Help Troubleshooting an Install

[Morgan]

Hi everyone!

I'm at a complete and utter loss as to what could be wrong with this custom install.  It was working fine some months ago until a random crash seems to have killed it.  I'm getting all the symptoms of a missing or corrupt NIF file but all the file paths are correct and I've confirmed that everything is there.  I get instant crashes when I load into Quickbattle or a mission.

As far as troubleshooting goes, I tried replacing the ship models with ones from a working install and no luck.  I even went so far as creating a fresh 1.1 install with basic Foundation.  Once I installed Wiley's Galaxy as a replacement for the stock model, that install died as well.  I've never encountered anything like this so I'm hoping someone smarter than myself can potentially look through this install and figure out what's wrong.

I appreciate any help that can be provided.  Thanks!
