EB2 approval notice, share info.

Just got my approval notice by mail today:
The above application has been approved. Prior to receiving your permanent resident card you may be required to report for biometric processing(photo/fingerprint/signature). Please do not take any action at this time. If you are required to report for this processing, you will receive another notice advising you of the date, time and location to appear.
If you have not received your permanent card or the above mentioned notice to appear for biometric processing within 90 days, please call this office at the number listed below.
I just did my finger print on 11/11/2007, do I still need to do it again? Does anyone else get this message in your notice? Thank you so much!!!
