Game crashes when I fire my cannons or broadsides.

[fatburger]

I just got a new Gateway computer running vista with 3 gigs of RAM and a 300 gig hardrive. The game runs great and graphics looks awesome even sailing works for the most part but when I fire my cannons manually or use the broadsides on my ship the game crashes every time. I have an ATI MOBILITY RADEON 2600 HD video card and the drivers are dated 1/09/08 and up to date because no newer drivers have been released in the last six months. Is anyone else having this problem and or know how to fix it? I try contacting gateway and pirates online support and they said there is nothing I can do unless a updated video card driver is release
This is so frustrating because of course my current quests require sinking ships and I can no longer do the pearl quest that also crashes when I use my cannons, I dont understand how this is a video card related problem seeing as the game runs great otherwise but thats what support is telling me please help someone. ARRRRRRRRGH!
