When ever i record a demo .....my character model permanantly faces one direction.The whole demo plays but somehow my mouse input isn't working.

Its been the same on two PC's and two different OS's

setup :
window7
deathadder mouse

Ive tried reformatting PC
reinstalling game
collected updates from different sources


Does anyone know why its doing this and how to resolve it?

It does it stock and on mods !
And its randoom....3 out of 4 demo's will be bad.
