AC Crashes when i assassinate Talal the slaver in jerusalem

[Trenalok]

Is there anyone that has this problem? ive tried 7 times now and every time it gets through it all fine, i see the cut scene after i kill Talal, and i getabout 5 seconds to run away, and then the game crashes. When i open AC again and reload, im back in the bureau and have to do it all over again... if anyone has found a way to fix this please help.

Also when trying to install the patch it comes up with an error saying "cant find the version info. update is aborting."

Specs are:
AMD Athlon 64 X2 Dual Core 4200+ 2.2GHz
1 GB RAM
Nvidia GeForxe 7600GT 256MB

I've had it crash on the escape from a couple of the different marks. Almost always in the same place each time (though different for each mark obviously) try killing him in a different area and heading out in a different direction. That's how I got around it
