Wii resets upon launching PM3.0

[SnuggleBubbler]

At first, I had successfully gotten everything in Project M to work, played it for an hour and then shut the Wii down and took out the SD Card
(Using the non-hombrew version, btw)
Now whenever I go to the stage builder, it launches Gecko as usual, but then after hitting "Launch Game" the Wii resets and goes back to the home screen. I have tried deleting and redownloading the Project M Files onto the SD Card and I have tried 2 different Wiis.
I am not sure what the problem is please help.

I've had a somewhat similar problem, but it just gets to the gecko menu screen, with a bunch of options, one of which is launch game but it comes up with an error everytime. nothing on the gecko menu works for me and afterwhich it causes the wii to restart/go to the home screen.
