Usbloader gx has had some major updates to it in the last few monts. Delete all of your gx files and get the new version. http://www.wiihacks.com/software-bac...loader-gx.html
That will stir up some debate.......best is an opinion. Wiiflow, configurable usb loader (cfg), and GX are all good loaders. Personally I prefer GX, but have found that cfg seems to be the most reliable loader.I wouldnt mind trying a new usb loader, but I dont know which one is best.
