.dll problems

can any 1 tell me how to stop these .dll problems when i join a server it says somthing .dll i dont know what to do

try reinstalling the game

if it says "client.dll is difrent than the servers" that means that you dont have the right version

Do you have ESF 1.2.1?
You might find you just have the 1.2 version.

See this link to get links for both ESF 1.2 and 1.2.1

i have 1.2.1

in that case you tried to join a server whit 1.2 or 1.1
atleast that is normaly the reason for that erroe

Well, with the infamous 1.2.1 crash bug, I think a lot of servers have rolled back to 1.2 for the time being. So what may be happening is that you're trying to join a 1.2 server with 1.2.1 installed.
