[Bug]map loads but player cant move

I had the game for about a week now, everything was working. Then one day..I loaded a map and spawned and I cant even walk forward. I've tried differet controls, I can change weapons, actually I can fire a weapon, but it wont stop firing till Im out of ammo.

??

specs:
1.8ghz Pent 4, could run 2.4..but long story
128mb Ati radeon
512 mb ram

What server were you playing on?

This just happened to me on every server I connected too
