Hey everyone. I extracted the last version (35) and i put in in \BtS\Mods\Caveman2Cosmos PS. This is the first time i use a mod in fact i didnt know that the civ 4 has mods. So, i opened from advanced menu. When the mod loaded (it takes about 2 minutes!!) i tried a gigantic map. Ofcourse game crashed (no error messages, it just exit to desktop) and then i tried Medium. Again the game just exit with no error screen or some message. Then i tried tiny and voila! The game loaded but when i pressed the science button (Top left) the game again exit with error message this time, something that i had no memory. Last i tried duel. And yes. It worked. I mean it loads, it runs, all the menus are ok and the first turn ended up just fine. I didnt went further. Oh! And All this with 1024X768, all setting at low, no antialising (0X). The game itself -with no mod loaded- runs just fine in 1920X1024, with all setting high and antiallizing 16X PC: AMD Phenom 9550 (Quad core 2.2GHz) 4GB RAM PCIE Nvidia 650SE with 2GB RAM HDD 250GB with 20GB Free Windows 7 Ultimate Any sugestions?
