Profile problem in Call of Duty World at War

[the_GIMP]

Hi. I got to the highest rank on this game an was playing yesterday an i got a blue screen of death then the game shut off.

Turned it on today and my profile name is still there but its gone back to the start.

I never got this BSoD before. My hardware is all fine.

Am running vista ultimate 2GB RAM 512 ddr3 ATI graphics card

The game worked ok for days before.

Anybody have this problem or hear about it?

Thanks!
