I have same problem. When I installed BIAB, part of the installation was to install IK Multimedia. Out of that setup, if I remember correctly, I had freebies Amplitube, SampleTank, T Racks. All free with full licences. I installed on 1/1/13 but only just opened up T Racks to check it out today. I had to register it but despite that I'm getting the noise every few seconds. From what I can see, this is the plugin/s in demo mode but I registered the software so how can this be so?

I've emailed IK Multimedia and will have to wait.

I'll be disappointed if this "FREE" software is a gimmick requiring further purchases of whats already installed.
