Hmm, I wonder if this is the same problem as we saw with The Sims 2, in so much as many players with nvidia or geforce cards experienced unexplained crashing, which turned out to be problems with nVidia driver, even newer versions.
It's still worth anyone experiencing crashing, freezing or other problems to pass the information on to the support teams, the more information gathered about the specific hardware/software being used at the time the more likely they'll be able to track down specific problems.
