HELP!! Nothing is showing up on the music center. I know for a FACT its loading and adding correctly just wont show up?? How to i completely restore.. 

Before suggesting please review all of what i have done already.

... " I have tried to following" 

...  reset music...

...  im using a external hard drive but transferred test folder to main computer C drive. To see.. Nothing helped...

...  I went to regedit registry and deleted everything to start over... still nothing 

SOLUTION! The only thing i can think of it somehow got mest up when it was adding the FIRST time... Is there a way i can completely restore to out of the box..?? Even admin library cause somehow is still remembering music center stuff  "i feel"
