Got my new P4 yesterday, and was going through the activation process on a Mac using Assistant 2.  Hung for about 8 minutes on the "Activation in Process".  Quit the app, rebooted, and next time I connected my P4, it went straight into the program, allowing me to select my P4, and updating firmware, etc.

Does that mean it was activated/registered?  Is there a way I can see that from my account when I login (not seeing it in "My Account")?

If you can start the motors it has been activated.

Yep - that definitely works.  Thanks!
