Hello, I recently purchased a used Eleven Rack from Guitar Center and attempted to install the expansion pack. However, I was prompted to enter the Serial No. and System ID and was unable to complete the installation. I then created an Avid account and attempted to register my Eleven Rack in hopes of receiving an assigned Serial No. and System ID, unfortunately, I was prompted to enter the Registration ID included with the original paperwork of the unit, which I didn't receive with my purchase. How do I go about acquiring a Serial No. and System ID? Any help is much appreciated, thank you very much.
