I have spent the BEST money ever! now that my allowance is all gone, let me help you out upon your purchase seeming to 'fail'.
It's not a fail, as it is simply different. so here's my story.
I went to the site, and did my purchase, and the Dload was very quick.
Close out the active Program your using ( Pro/ Deluxe / Designer)
Opening the DMG, all is 'normal' ( Mountain Lion)
After dragging the new app into my applications location, it seemed to 'link'- a momentary blue highlighting with my ( Pro) active Version model ( Or Deluxe)
I assumed the Version 8 Pro would have the Statement within the "about" that it is a ( Pro PP): no- It will open as a standard pre Power Pack title.
In the upper end ( I'm playing lots of Revenge of Zuma, @ the bottom of my apps stack) of the apps stack is where the Power Pack lives all by itself. I checked out the 'get info' and any of the Turbo CAD Mac programs are dimmed out, so no- I'm not going to be opening it with my ( Pro)
I gave it a double click, and now I got the program activation location, copy etc. Passworded into the addition, and at that point your good to go.
( Now here is where I got a tad confused, so I did a restart, and earlier I had Skype die on me, so I closed others out, and needed to unplug my mini Mac to get a fresh restart. ( you won't need to do this)
Upon opening your ( Pro/Deluxe) the Power Pack will be included,even though the titling does not say so. The 3rd Block from the right ( left of Window)will be Power Pack, all ready to play with you!
Have fun, as I sure will be! Thanks for your time!
