Well, sometimes things can solve themselves....
Last night my laptop did a major Windows update, and lo and behold today I have been working with sketchup and it's running just fine.
Even rendering works without glitches and bugsplash.
Sorry to bother in this matter.

Laptop is a Lenovo G50,
came with a 1 TB HDD,
16 GB ram,
I7 dual core 3.5Ghz processor

Ever since I got my new laptop Lenovo with Windows 8.1 Home edition and installing SketchUp 2015 Pro, when I am working with SketchUp it takes on common bases 8 minutes from starting until the SketchUp crashes.
I have tried with several setting and adjusting the bios without any changes.
My old laptop with Windows 7 and SketchUp 2015 Pro worked just fine, no glitches at all.
The podium rendering program doesn't recognize with legal serial number either.
Has anyone experienced something similar?
Any input would be helpful.
Thank you

I wouln't worry after a couple of hours only - maybe after a couple of days...

Does the location have any impact of how fast it goes to get licens through? Living on the westcoast of USA.
When I bought my upgrade from SU6 pro to SU7 pro I had an email within the halfhour with the new licens-code.
However, I experience the SU7 pro slower than the previous version and also the component library (from Google/sketchup) is a pain to work with. Can't find as before a complete architecture libraryto download, even though I have used the walk through provided by SketchUp/Google. Any suggestions how to get hold of those libraries.

Have a nice weekend everyone.
