Spring RTS Engine

Hello guys,
I have this annoying problem that, when i start the spring battleroom there are mostly only a handful of people... but sometimes there are about 200 people... i guess this is another server, but when i start my the battleroom it randomly goes to the first or to the second server. But of course i want to be connected with many people to play with.
I hope you understood my problem so that someone may help me.
Thank you in advance

the client is bugged, dont think there is anything I can do about it, make sure server adress is taspringmaster.clan-sy.com (in the options)
