So I decided to play through the excellent TMI series again.
Two days ago I started a new game in episode 1 and played to the end. Hooray.
I went to launch Episode 2 tonite and it crashed when I clicked new game. The same happened on other episodes.
Thinking I might have corrupt copies, I redownloaded all episodes.
Now ALL episodes crash if I try to launch a new game. Episode 1 will however Resume Game just fine. Though it crashed when I exited. Episode 1 crashes if I go to Load and Run and attempt to load the save that way.
That tells me that wherever the games are keeping the save files is corrupted but I can't find it on my hard drive.
I'd mentioned that a download of the BTTF game ran just fine.
