Yup... Steam patched a new update and the Mega Trainer 1.02 for steam no longer even knows when the game is running.
I am guessing the regular retail version got patched also.
I am crossing my fingers that this game isn't too old for updates.
It's not a game patch. It's a steam update that has caused some problems with certain titles. On the steam forums they say you need to exit steam and start it back up again and it should fix it.
Now how that affects the trainer I don't know.
