I need some help

i have a major problem with gothic right now and searched the faq for the game and countless forums but none of that actually could help me

Gothic just crashed with no application error and i cant close it.. I tried alt f4 and it does not work..control alt del does not either cause iam playing from a net station that has task manager locked..I have no access to desktop screen and mouse..the background seems to be in game.All i can do is hit start but there is no way out of there either because windows does not have run so i can type msconfig to kill the gothic application..oh and i opened the dvd rom too!!

In my fact my problem relies that i have allready play 15 hours in a row and i dont want to restart my pc(deep freeze will own me) and lose the save
I would appreciate any help thanks ~

its ok problem solved :-) thank you

Good to hear your problem is solved. Gothic is a bit unstable. Save often.
