Ok, long story, I'll start from the beggining.
I tryed to connect to server, blablabla, downloaded the files, unzip, etc.
Then, executed the rmserver.exe (I had the .xml and the data folder). Nothing happened, the process, didn't even start. I asked for help to a friend. He told me to try with other .exe from other server. I did. It opened this time. Tried to register as the web says, with the username_M/F. Enter, and got 'Disconnected from Server'. The server is ON right now (or the status says so).

I have 2 computers, so I have proxy. Also tried to connect in the proxy computer, same error.
Any idea =x ? I don't know what to do x__X
Thx~
