Cubase 8.5 with demo Guitar 2 - keeps crashing - would like to buy but

I am interested in purchasing this product.
I have a monster Windows processor 10 PC computer with endless ram and am using cubase 8.5 with a UR44 - I never have any crashing issues with cubase ever.
It keeps crashing on me as I try it out Guitar 2 - in Cubase.
Anyone else have this issue?
I notice an “Exclamation” mark on the Midi Guitar 2 → interface → in my Cubase next to the words “Latency 11.6 MS 512 samples @ 44100 hz”
