Call of Chernobyl is a free-play sandbox mod for S.T.A.L.K.E.R.: Call of Pripyat created. But I also have clear sky and it works fine.įor S.T.A.L.K.E.R.: Clear Sky on the PC, a GameFAQs message board topic titled 'Cannot open file 'fsgame.ltx' error.anyone else get this?'ĭiscuss the topic 'Can't start CoC' in the Support Call of Chernobyl. File/s ever so slightly corrupted while downloaded and the problems did not manifest until now? I cannot think of anything else. Themken: Hmm, maybe a fault in the memory or hard disk corrupted the file? That can be caused by misbehaving power levels too (too low or too high voltage, too little or too much electricity) so the RAM/HD not necessarily broken.
