sound blaster live gamer

nothing running in the backround
it happens on all servers
i tried reinstalling
it just started doing this yesterday after the steam update


*UPDATE*
i get the same error in CS
so im now thinking it has nothing to do with NS
but with steam or halflife

MR_DO

turns out it was a router problem
no help needed now
