I suppose there is a memory leak somewhere and every 8 hours or so it may be a good idea to save/exit and reboot your PC;4

Crashes seem to be caused by two things -- 1) slow/unstable Internet connection since Steam runs in parallel with the game; and 2) memory leaks (check Wikipedia to find out what a memory leak is)

Generally, the more RAM you have, the less you will suffer from memory leaks (not only in FONV but in any software)

I always hated piracy as it helped ruined good gaming companies and kept many good games from being made.
