The popup displayed during first launch after install, on two machines. It said something about version being slow because it included a debugger, or something to that effect.
As to applying the license: On one machine I selected "Apply my license" from Help. The "My Details" (and "My PowerTools" and "Options") displays but incorrectly formatted to the screen size (too large so I can't fully see the Options buttons). I type my name and email associated with my Platinum VIP license and then press Enter, and get the error "Your license to use jv PowerTools has expired, please renew your subscription at www.macecraft.com if you wish to use the software."
On the other machine, I can't get to the "My Options" screen or even the About screen. When either is clicked from Help on the Home screen, the program blinks "Loading, please wait a second" and then returns me to the Home screen.
