Again, I'd like to apologise you are having this experience. You are so polite, and I am so sorry this happened to you.
Now, it's nearly midnight where I am, so I'll look into this more tomorrow, but maybe you can try running the program as administrator? Also try compatibility mode (Windows 7). Also, move the game file to the desktop.
If that still doesn't work, I will make a new save for you that starts there so you can resume from that moment. You will need to reset your skills at the trainer to avoid soft-locking the game, but everything should (hopefully) still work from there.
P.S. Just to double check, you didn't mod the game in any way, right?
