Game Freezing at same spot every time
 

I've searched this site & google already

3rd SP mission. Thru the town, into the Garage secure the weapons cache. Get intelligence. Then head out back and jump on a truck...game freezes. PC needs reboot. Same every time. Any advice appreciated

I've patched the game
