Creating multiple DKS

Hello,

I am new to these private servers but i can't imagine why i am not able to create a death knight on a different server than the one that already has one because it tells me that i don't have any level 55 characters.... even though i already have a 55 as well as a death knight on one of the servers?

Any clarification would be awesome.

Thanks

you need a lvl 55 on the server you want to make the dk on.
