On v6.1, I can get past the EULA. BUT, there seems to be a problem typing in the serial number. I can only put in 3 out of the 4 needed characters in each "block". Seems to be a font size issue.
EDIT:
Sorry, but this is my first day using Crossover. But, anyway, I downloaded Steam (I got HL2: GOTY) and noticed it installing fonts. So I decided to give F.E.A.R. Combat another try (in the same "bottle" as Steam). This time I was able to put in the serial and the game installed fine. BUT STILL NO GO!! :( I love this game and hate restarting my whole computer to boot into windows to play it.
