First thing is to upgrade to SketchUp 2014 or above.
It has 64bit and a ton of bug fixes. Plus 7 is not supported anymore.
I would not say you're in for a shock. Just more goodies around these days.
The Premium General Direction Discussion is where Premium content and offers are distributed.
There's also a normal and free discussion forum for all things SketchUp and Layout.
Just browse around and find your feet.
Welcome back.
