I tried the patch that was provided to me in a link in an e-mail sent to me from Metaboli.
It doesn't work. The same error remains. I replied to the message as such and am waiting for their response.
The fact is, I don't care what the problem is, I bought the game and I would like to play it.
For me to install the game on another machine to patch it, and bring it back to this one is just crazy. Not that I won't do it, but to go to such extremes is not my idea of fun.
Edit: And no, it's not my system that has issues. I've run Sisoft Sandra Porofessional on it and checked everything.
