Many thanks for your replies. Barry, don’t quit your day job. English is not my first language, and dissapointment and its evil friends (two s’s and one p, or is it two p’s and one s) always cause me trouble.
I paid $400 or so dollars for Sketchup Pro (v. 8). Is there a reasonable expectations that Sketchup and the 3D Warehouse to continue to work? I think yes. Would I pay something for an upgrade? I would consider it, but $150 is a pretty hefty sum for something I already paid a hefty sum for.
My Macbook works just fine, and a used computer (may as well be new for the prices they want) just to be able to use Sketchup is a bit of a reach. The computer has Mountain Lion and is as far as I can take that without a new (or used) computer. The new version of Sketchup will not even download because it appears to be incompatible with Mountain Lion.
Out of reach means I can not open the 3D warehouse. From inside Sketchup, I do a search and get nothing. Go directly to the 3D Warehouse and get the Good News, Bad News box. Really? Just like that? No notice, no warnings, no work arounds?
Fortunately for me, I downloaded Sketchup 2014 at some point (due to file format changes in more recent versions) and I have confirmed that it will work with the new 3D Warehouse. I will try the other steps today…
Planned obsolescence seems to have made it into the software business, and I shall be careful in the future with what I buy.
