I have attempted to join the Beta Server but it tells me that I am multi-ing .

Try registering under different name than the other ones you use...

and change it back once you're in.

no, this is because we are in the same school, so we use the same internet, i am surprised he actually posted this question on here when i told him the reason why...

....

I am not sure if that is the reason or not. It could be as I have heard it from others, however the rules have no problem with multiple people on the same internet services, it states per PC. As well, I know that when I started, 5 or so friends started this game in school and we never had a problem playing. As well, a housemate of mine plays ZE too (different PCs) and we have never had a problem from using the same wireless.

I don't know what the problem was, but it worked now.
