Regarding Amp Farm. I found that I had to upgrade to Amp Farm 3 as I was getting the same error. I am reasonably certain that this would apply to your issue too. Your iLok.com view of your iLok authorisations will indicate whether you are licensed to run version 3 - it is not a free upgrade from earlier versions. Your iLok will state "Amp Farm 3" as the product name, rather than the less obvious "Line 6 Amp Farm HD" which refers to earlier version(s). If your HD2 is relatively new, it still may have shipped with an older license for Amp Farm, as ours did, even though Amp Farm 3 has been available for some time now. I have to admit that I didn't perform any further troubleshooting than this. At the time I couldn't find any official documentation indicating that 2.x was unsupported in PT 7, so maybe you could persist on that path with Digidesign Support. You may also be able to argue if you have recently purchased the HD2 that you would expect it to ship with the latest versions of the plugins and, perhaps, Digidesign Cust Service will pop the appropriate iLok auth in your account without charge.
