I just booted WiiMC for the first time on a 3.1U Wii without 202 installed. I was configuring the SMB option when the screensaver was activated spontaneously. My Wiimote ceased working, and I was forced to do a hard reboot. Upon trying to start WiiMC again, I get a black screen and my Wiimote ceases to work again.

Could this be compatibility issues with 3.1U?

Thanks
