Thanks Dan,

I figured it out, but it did take some time. I had previously registered both amplitube and sampletank, but had not written down the serial numbers. So, I went to the IK Multimedia webpage, logged in, clicked on go to users area, clicked 'my products', and in that list were both Amplitube and Sampletank, with their respective authorizations. With those two serial numbers, I launched Authorization Manager from my computer, logged in again through it, and typed in each serial number. (I had to launch the authorization manager twice, maybe not necessary.) Anyway, once I had gone through those steps, the expiration warning stopped and all seems to be operating normally.

There's has to be an easier way.
