Game crashes: questions and answers.

Hello! The game usually crashes only on certain maps. It didn't crash on the original versions of the game either; I completed them and started playing "Throne of the King," and then, in the second week, it started crashing, either during manual combat or during the computer's turn. My system fully meets the game's requirements: processor - AMD ATHLON(TM) 64 PROCESSOR 3200+ 2.01 GHz, 4 GB of RAM (but because I have a 32-bit operating system, it only sees 2 GB), video card - asus eah4650 series, driver from 2009, sound card - soundmax integrated digital hd audio, driver from 2005. I installed the drivers from the disks that came with the computer. I contacted the game's tech support, but they couldn't help. I don't even know what to do anymore. I haven't updated the drivers because there are many of them online, and I don't know which ones I need. I tried installing DirectX 9 from the licensed disk of "Tribes of the East," formatting the disk, and reinstalling everything, including the game, but it still crashes. Oh, and the operating system is 32-bit XP pack 3, but it also crashed on different versions of Windows 7 64-bit. Different versions of the game crashed as well, such as the licensed versions 3.0 and 3.1. It's just that there are some maps on which it plays normally; most of them are like that, but there are some on which it crashes. I updated the drivers for everything I could find using the SlimDrivers program. Now, the video card driver is from June 2010, and the sound driver is from 2007; I and the program couldn't find anything newer. It didn't help. In the administration log, the error is recorded as error "Code [ID]: 1000" or "Code [ID]: 1001."
