@maciozo: Did you see the newly updated v1.07 patch for F.E.A.R? I just checked it out and it contains an Activemark EXE as expected, however, after dumping and fixing it I can get this one running on my UK game after updating to v1.07 whereas all the other Activemark cracks (1.03, 1.04, 1.06) never worked
Been playing this all day today and not had a problem, except one hard lockup just before loading Interval 03 Exeunt Omnes. But I did have 10 folders open and a browser in the background as well as messing about with the detail levels during the game and having it loaded for more than 2 hours

Loading the game back up and going to the same place was fine, no lockup, and it loaded the next level. Also used the 'maphole' cheat to load each level and they all loaded without a problem.
If anyone wants to test this 'v1.07 crack' try it here:

However, it was dumped and fixed under XP with SP2 installed so it may not work on SP1, not sure how to fix imports so they work on all OS'es
