Hey guys I seen the whole guide on installing the Rock Band DLC on your Wii and that has worked out great for me except when it comes to downloading. You see I followed the guide to the letter and every song from the Gorillaz to Queen is unlockable and ready to download. There is one problem though, when I click to redownload it just says "Retrieving Data" and then it comes up telling me that there is no room on the Wii system memory and to move things onto the SD card (I have a 1 gig one in the Wii). I am very confused because there is 1500+ blocks on the Wii and about 7000 on the SD card. It is getting me quite worried that there might be something wrong with it.

You see I have a PAL Wii now with an American shop channel. It seems to work fine for everything else (like playing the songs and such). I just can't figure out why its not letting me save. I checked the memory card/system memory and there is no DLC list at all. I think this may have something to do with it but I'm not sure what.
