Hi,
I've got th same Problm since about a month, I tried everything, reinstall Half-Life, reinstall esf, reinstall both. Nothing works, What graphic Card do you use??? May be that's the point.
Do you have Windows XP, too??? I will format my Comp. the next days, may be that will help!!!
If you find a solution, please Tell me!!!
I hate hear everybody talking about this great Mod and I can't play it!!! Urrrr!
