AB Motion Analyzer Activation

I went to use motion analyzer this morning and it is asking me for a activation key. I thought it was a free program as it is in the integrated architecture tool set.

Anyone else ran accross this. I find info about it on the ab site but no catalog number to buy it per se?

I see now you have to register to get a key for the full version. If it is a free software then why go through all that. Just put the full version on the disk. Sheesh.
