LMS can't find player

I'm running LMS on a Windows 7 computer.
It consistantly says it can't find a player.
My player is a SBT, connected wirelessly (wireless signal 78%).
I've told it my Library Name, and given it the IP address for the library.

When I choose My Music, it shows Connecting to ip number.
After a bit, it says Problem Connecting.

I don't know what else to do!
