How do you reset the demo time limit?
Here's my situation.
I got the game for a Christmas present via Steam. Cool, but now I'm not allowed to play it until Christmas -- wife's rules! I can PM support here for proof that I do indeed own the game via Steam. Or if somehow you can see my Steam profile it's "escapedturkey"; it should show that I own retail version, just not installed.
The Steam demo didn't have a time limit, it only had a limit where if you finish one of the first missions it stops and you can start over. However, it turned the game into a real version (which is fine) after I got my gift.
I read about the new patch being a demo, so I am allowed to check it out (wife's permission). However, there is a time-limit and the game expired. I tried removing registry entries, reinstalling, etc. and it still says my trial has expired. Yeesh!
Now I can't even play the game nor demo until Christmas.
