How do I get my games to work again from USB Loader GX?

My Wii was jail broke for me and it cost $80. I have a bunch of games on it and it worked fine until recently when it was unplugged then plugged back in. Now when I go to my USB Loader it gives me a black screen with codes and at the bottom it say Reloading in 5 seconds, but it doesn't do anything. HELP!!! I can't afford to pay someone to fix this.
