Trouble on Vista

[AntiMatter22]

So I know lots of people are having trouble with crashes out on the oceans while using Vista. I've tried to update my graphic/video card, driver, and whatever. However, I still can't seem to get it to work. I'm using the ATI Mobility Radeon 2400 HD on my XPS One. I know that that card is not one Pirates supposedly supports, according to their workaround ideas in "Known Issues." I'm basically stuck so if anyone could help me out here it would be greatly appreciated. I'm semi-knowledgeable when it comes to computers - I can try to read "it," find "it," and do "it." Thanks.
