client.dll

I have a original HL serial Key but when I try to connect on a ESF server it says that it can't find this file "client.dll" in the ESF directory, but when I look in this directory this file is there.

What should I do?

Update halflife to 1.1.1.0 with the update patch.

I have this version and also have CS 1.0.0.5 version.

You can't have both versions man, you're doing something wrong. If you have CS then you need the 1.0.0.5 patch, if you have HL you need the 1.1.1.0 patch.

I have reinstalled my HL and ESF and also have updated the HL and now it is working fine.

Thanks. :yes:

The only problem now is the mp3, that isnt working right... I don't it is my pc because a have a Athlon 2.0 and 512 RAM.
