CTDs when loading siege battles

[poisoned goat]

I've been running into endless CTDs ever since I formatted my computer. Before formatting, I could play all kinds of large-scale battles on SS6.3/6.4 without any problems. However, currently my game crashes on loading battles. I'll try to describe the problem to the best of my ability.

Running M2TW from steam, SS6.4
Submods: Weakened heretics, faster loading times. I don't think any of these will affect loading battles.. I also tried to install G5 RBAI to get rid of the CTDs but it didn't help at all.
I tried everything listed here: http://www.twcenter.net/forums/showthread.php?t=380883 but nothing worked out. I couldn't install DirectX 9 because I already have DirectX 11. I hope this doesn't matter.
Updated graphics card driver to the latest version. I'm using nVidia GeForce GT540M, if that matters.
Reinstalled SS6.4 twice, didn't help. I didn't reinstall M2TW because it takes forever to download on Steam.

System log: pretty useless. I don't see anything that could be the problem..

As for the problem itself, the game crashes upon loading almost all kinds siege battles. Sometimes, I get a popup saying my graphics settings are too high, but it still occurs when I lowered it to the absolute minimum. My computer should definitely be able to handle it; before formatting I could fight in huge cities, citadels, with 4 full stacks on huge unit size. On the very rare occasion that I don't get a CTD, the battle lags like hell..

Does anyone know how to fix this? I tried almost everything and nothing works. Many blessings to anyone who can figure this out.

IT WORKS LOL. I just tested on 2 different battles where I crashed a million times previously, and no more crashes!

For reference, I changed it according to instructions here: http://superuser.com/questions/23144...ead-of-onboard

Thank you!!!!!!!!
