Help Help Help Please Cant Play Esf For Some Reason!

Ok i started playing about 2 days ago. Yestarday i had to reformat due to a virus and now whenever i try to join an esf game it says Due to a problem we need to close half life, or something to that effect. Its basically windows xp's equivilent of windows 98's "This program has performed an illegal operation abd will be shut down". This never happened before i reformatted.

Its probably because u dont have the fmod.dll file!! Check the sticky in Newbie Central about that!!

i reinstalled ESF and it worked....
