Can't get back to the Wii Menu

When ever i go and play a game that i have downloaded from the Wii Shop Channel and try to exit to the wii menu it will go black and not go to the wii menu. This only seems to happen then i try to exit channels. I can however exit the disk channel.

Do you have priiloader installed? It's the only thing I can think of that might affect this...

Actually, never mind i figured it out. I had a wbfs formatted flash drive in the 0 usb slot and for some reason it did that, pulled it out and it worked fine. Thanks anyways though.
