Ive got some hard times making this game working properly, all the time i had hard freezing and i needed to restart my PC. Ok i just removed all add-ons previously installed and voila! game runs perfect - no hick ups, no freezing, no crashes anymore. I think i can live without these - 21vGlider, APC russian, BAS delta rangers and littlebirds, Editor Upgrade 1.02, Tornado, mortar.
