Game crashes on stealth bomber op

[killbill77]

Hi there all!!! Really annoying this! All my other games work- but on black ops it crashes every time on the stealth bomber mission when your looking down on the team and commanding them in night vision from the stealth. The codev reads:

Code texture 6 'shadowmapsamplersun'
Material-'mcfmtl_15_veh_sr_decal'
Tech-'pimp_technique_probe_8clf02d70'
Techtype=10

Any one the remotest idea??

thanks craig
