Ok, got it figured. It was a filepath problem -- the space in "StrikeFighters2 Korea" was causing the issue: C:\Users\corey\Saved Games\ThirdWire\StrikeFighters2 Korea\Campaigns
I changed the application name and corresponding directory to "StrikeFighters2Korea" (oneword) and the campaigns are showing up now: C:\Users\corey\Saved Games\ThirdWire\StrikeFighters2Korea\Campaigns
Hopefully this will help out someone else if they have the same issue.
Thanks again.
