WiiMC nor MPlayer not reading USB
WiiMC only reads my SD card, not my external hard drive. This worked at one point - I do not know what changed to cause it to not work.
MPlayer does not work, but all other programs are reading the drive without a problem, including USB GX Loader.
In order to fix, I have downloaded and installed the newest WiiMC. After some googling, I have attempted to use IOS58 downloader to install IOS58,which, is what may be causing problems. When running that app, the bottom left indicates that I am running IOS 58, but attempts to install anyways result in "Installation failed!" (with no further information).
What further steps should I take to diagnose?
