Hi everybody. I have a problem with crashes to windows too. I recently change my computer, I bought another one because in my older computer I could play hardly without problems of crashes. I'm playing with 911 first responders and I have installed the LA mod 1.5 and I use it to play. When I play in a new game, it doesn't matter is free play, campaing, neverendless, challange... I can't play more than 10 minutes, the game never let me play more than 10 minutes, always crash to windows without error message. I tried a lot of thing for solved it, I update my grapich driver to the lastest, I change the resolution, close antivirus, firewall... Nothing works. My computer characters are: DualCore AMD Athlon 64 X2, 2200 MHz (11 x 200) 4200+ with 2,19 Ghz and 2GB RAM Grapich card: ATI Radeon X1200 Series (256 MB) with lastest drivers. Operating system Microsoft Windows XP Professional My logfile: Logfile In logfile appears some error like this: ?ERROR: dynlight.vsf Version 3.0.0.0 or higher required! what does it mean? Could be the origin of the problem? Thank you very much for the future help, I really wish to solved for play 911 without problems.
