Wii console not connecting to Rock Central server

[Ryno90]

My console won't let be do anything online with Rockband2 except download songs. I use a wireless connection and checked and restarted it a few times. I can still do everything else online with my console it just won't let me do the battle of the bands, or any sort of online multiplayer. every time I try it gives me an error message with an error code of 20100

Please help me!
