I have looked at the textures involved in Andromeda and I cannot find any problems. I run the textures on two nvidia and one ATI card here at the house and all three will play any of the MH maps. I've done two test reinstalls and countless computer restarts, even trying my level darndest to crash andromeda on a private testserver.
I have looked at the textures in ed and exported all the andromeda ones to photoshop to check for errors. I can't find anything

In short, I am sure hellfire is having an issue with something, but I am equally sure it's not within the texture package. If a texture was causing the crash, it would vomit some sort of error in the utlog. The fact it doesn't leads me to believe there is likely some sort of hardware issue. I'd guess RAM but it could be motherboard too. The texture package is frontloading his system probably to the point of swapping and somewhere in there is a hardware issue. I'd bet if he loaded a selection of some fairly long maps with large mylevel packages that use a bunch of the new textures, he's probably get the same error.
