I'm not sure if this is the reason, but with trial and error, it seems to be the case. I had everything working well with RB2 backing up content to the SD card. Then I installed Freedom, reinstalled SM4.1U, and preloader with the hacks from the wiibrew site. Content backup no longer worked. I downgraded to 4.0U, and upgraded to 4.1U again, installed cIOSCorp 3.3, and tested again, and it worked again. I installed preloader again, and it doesn't work again. I am thinking it is because of having the IOS Reload hack enabled. Should disabling this stop that from happening, but still allow for preloader install? Thanks for the input.
