You'll need to provide a bit more information than that. When exactly does it crash, on the splash screen when the game is loading or when you are loading a save. Is there a message when it crashes?
Thanks for responding.
It is the start screen of the game when the game is loading, there appears no option menu. I get no error message, just:
Warband has stopped working and will close. * With 85% of the loading bar filled.
In version 6.0 it was the same problem, played in version 4.0 without problems.
If it is a memory issue, you can try ticking the "Load Textures On Demand" option in the configuration menu before you boot up the game. Your 9500 GT is an entry-level card from 2008 - so it could either be an issue with GPU memory, or it could be your RAM. A stick of RAM doesn't cost too much and isn't terribly difficult to install (though your local computer store can easily provide you with, and then install, a new stick), but if it's your GPU's memory, you're just going to have to pony up for a new card. Newer entry-level cards can run you $50 to $100, and also isn't terribly difficult to install (though if you're not computer savvy, you're better off getting a store to do it - it'll run you an extra $50 or so for labor, most likely, but if anything goes wrong they'll be liable for it, most likely).
My personal recommendation on a somewhat older budget card is the GeForce GTS 450. It's a mid-level card from 2010, and it's what I have in my rig back home (not currently with me, sadly; relegated to the laptop!); on that rig, I can run ArmA II just about maxed out, along with hundreds of other beautiful games. I'd also recommend beefing up your RAM anyway, just because 2GB is very low for gaming. All together, if you're going to get that card (or any $100 card) and some RAM, going to a store might run you about $150 to $200. You can also pay somebody to assemble a new rig that would be far superior to your current one for $600 to $800, though I know that it's hard to find that kind of money laying about.
At any rate, hope some of that helps, and sorry that you can't run the mod - it's quite fun! Also, thanks for the reply about the prison bug, Cozur. Wish I could help; I've no idea about M&B modding, though my first thought would be that there's something wrong with the scenes themselves (the actual existence of doors within them, that is), though you've probably got a better handle on it than I do regardless. Good luck! And looking forward to 0.9.
