When playing Civ4 Warlords, I have found that after a while the game spontaneously turns off after starting new turn. The crash is caused by faulty operation at the address 0x00593487 in civ4warlords.exe, and it eventually occurs in any re-play I have tried to date. Here is configuration of my system: HP Compaq Presario R3000 notebook, CPU - Mobile AMD Athlon 64 2400 MHz (12 x 200) 3700+, Memory - 2.0 GB DDR SDRAM, Video Adapter - NVIDIA GeForce4 440 Go 64M, HDD - TOSHIBA MK8025GAS (80 GB, 4200 RPM, Ultra-ATA/100), DVD Drive - _NEC DVD+-RW ND-6450A, OS - Windows XP Pro SP2. Could you please advise me how to fix this problem? The game save is attached.
