I tried to purchase JABB3 over the weekend, but was denied the upgrade because my serial number was incorrect. It is the number on a white strip of paper inside the JABB disk box that I purchased a few years ago from Garritan. Any help would be appreciated.
Tom, I'm pretty sure this involves the rigamarole of going to the Native Instruments site, going to your user download page, and requesting for a new serial number to be issued. Then you have to register it with their Service Center - THen you can upgrade at the Garritan store site with the new #. Pretty sure that's right.
