...uninstall! I was being impatient as I don't have the internet at home, and when I was installing REV19 I was missing one of the wad files (IOS38-64-v3867.wad) to use as a base, but I had a wad file called IOS38-64-v2978.wad or something on my computer, so used that instead (note the different number after the "v") and just changed the name. It was stupid, but I thought it probably wouldn't make any difference. Unfortunately it did. It said everything installed ok, but then it crashed. Everything seems to work normally, except when I load up the DVD backup loaders, I just get a black screen, and everytime I try to install a new cIOS249 (using all the different installers, even a really old WiiGator thing from when they first got backups working) it crashes whenever I get to a screen that mentions cIOS249. This even happens with the cIOS REV19 installer thing. I tried to use AnyTitleDeleter to remove the "IOS249" file, but it won't for some reason and just says "error". Btw, the only problem is that my backups won't load now. Everything else seems to work fine. Thanks in advance!
