Major, I think you may have run into this problem. I think you may need to FSCK the thing.

I had something similar happen when I tried one of the alphas and then reverted back to 2.0, just like you did. My player works perfectly fine now, and I do all my updates with Emplode 2.0 final.

One thing to check is make sure you're using emplode 2.00 final and not emplode 2.10.
