Hacking USB Loader GX help

[zxthehedgehog]

I recently installed USB Loader GX, and, though I've installed games on it, they refuse to load, kicking me back to the Wii Menu when I hit Play. I have D2X cIOS, and have tried multiple games without success.

Any help?

P.S. I can run WiiWare and VC fine, as well as HB forwarders and HBC.
