Thanks in advance to anyone who tries to help me. My first problem occurred when updating from CIOS rev8 to rev10 after hearing that it is currently the most stable version. After doing so, Neither Rock Band 1, 2 or GH: Metallica could detect my usb microphone. I even tried updating to rev11 and rev12 and had the same issue. This problem was solved however when i reinstalled CIOS rev8. What could this mean? Another problem that I'm having is with my SD card. Whenever I download a song from the music store it says that it is backing it up to my SD card. But, when i download more songs, they continue to take up space on my Wii. If i reset the game, it always gives me the message that it is backing up the songs that i have saved on my internal memory but it is obviously failing to do so. I have an NTSC Wii on system menu 3.2U.
