I've been using Chunkmerge and Nifconvert, [for converting custom models to Skyrim Nif Format and adding collision], for 2 whole weeks now.
The whole time it was working flawlessly. Now, whenever I set everything up, [when I click convert, in the program], the program freezes then says:
TODO: < Description > an unexpected error has occurred. Shutting down.
^ then pressing ok, it exits Nifconvert or Chunkmerge.
I have no idea why it started doing this nor can I fix it. I've cleaned up my computer. I've re-downloaded the program. I have done everything I can think of and it still does it.
