is there some new patch out that i havent heard of? i tried joining lie 4 servers that i normally play at and it says different dll. they were working a few days ago

fmod.dll or client.dll

If it's fmod it means you installed something that changed the fmod.dll in your Half-Life directory.

If it's client, you could try reinstalling.
