Can you please install the game elsewhere, I see it has been put in C:\Users\Goncalo\Documents\ which is quite unusal. If you have another hard disk partition than C:, that would be better. At the very least, try installing it in C:\games (or juego ) instead, and verify you have several GB of free space also, this might be connected to a lack of HD space.

I guess the issue was that I copied the game folder directly from my other laptop to this one and something must have been corrupted. Now the game works fine.
