As soon as I activate the trainer and try to save, I get a "Save Error" message (see attached picture). The game's auto save does not save the game for me either.
No attachment. Zip/Rar it first.
Is the save feature in Aurora turned on?
Maybe try turning that off to see if it does anything.
I wouldn't think that would cause this problem or we would have thousands of complaints about it instead of two. It's probably some weird combination of trainer/editor options used and your armor or class or stats, etc. It could literally be anything.
