Am playing version .91 beta with the newest multi-media downloaded as of this morning (ver. 1.0.039 I believe). For the past several days, I get about an hour into my game and I get a CTD everytime. I'm playingi a large map with 4-9 other civilizations at either beginner or normal level. Habital planets are set to common, planets and stars are set to occasional, tech rate=normal as well as the other options. Brand new Nvidia driver (8.1.9.8). My machine is rather long in the tooth but still servicable. A P4, 2ghz, 512 meg ram, with an Nvidia GeForce 5700LE 256ram video card with a 60gig HD with about 20gig still available. Any help as to what may be causing these crashes would be most appreciated. I have started new games after each download too if that helps.
