K-Relay problems

So recently i have been playing around with multiboxing and stuff and i wanted to get k-relay and test that out as well. so i hop onto a client and i open up k-relay and when i try to connect to the proxy server (BTW yes i did turn the proxy on) it gives me

Socket-Server Security Error: Error #2048
Connection failed! Retrying...



and when ever they are running my computer starts to lag like crazy.

Can any one help me with any fixes or things i have done wrong? thanks

Lock please, i have solved it i needed to put the ip of kabems servers into the "host" file
