I'm getting the same problem, running base game. i'll try the FOC one as well to see if it works for both...GoG edition.
*edit* I noticed my game version is not 1.05.48825 it is 1.05.48808 from the GOG gold pack.
*edit2* FOC is also the wrong version it needs 1.01.58933 and my version is, 1.01.58910.
