Hacking Backup loaders won't detect usb device at all!

[Gamerdude160]

Hi, This is my first time posting but I need some help.
So I use usb loader gx, which has worked great so far until now.
I had a couple games, they ran great, but then i added one more to my usb and all of a sudden I cannot play anymore. I've tried removing all games and putting one or two, and even the original ones I used before. Now, wiiflow and usb loader gx wont read my usb at all!
I ran usb loader gx through a usb to see if that fixes anything, but it just hangs at "initlize usb device" then when its done hanging it says a usb cant be found. I don't know whats wrong and now I can't play my backups. Please help!
