Cubase 8.5 trial. Lots of BUGS!

I have been testing out Cubase 8.5 trial. I have come across a number of bugs which are concerning me.
1.When I install it says it cannot find a file for Groove agent. Groove agent Se acoustic kit not found.
2. If I install updates from the site I can no longer record MIDI.
3. I have tried to record a VST from Sonar call Drop zone. it records it but then the sound will not stop.
4. it crashes a lot when I close down. Cubase has stopped working…

I have a new generation Focusrite Scarlett 2i4
windows 10.

Any ideas?

I love the new format and the latency is amazing but if this does not stop I will not buy it.
