Urgent call for help - Recvd GC but status recently changed back to fingerprinting

Hi guys,

I recvd my GC in June 06, but today I got an email and my online status changed "..., the results of your fingerprint review for your I485 Application to Register Permanent Residence or to Adjust Status were received, and processing has resumed on your case. We will mail you a notice if further action is needed, or when a decision is made"

Any clues?? Is this normal??

Thanks in advance.
