cubase artist crashing with kontakt instrument

i am running cubase 9. It runs fine accept when i run kontakt. mostly spitfire audio’s albion one library. i open the strings patch, and the purge icon at the top left of the interface goes crazy like it it reloading samples constantly. then if i touch a key or click with a mouse it locks up cubase and i have to force quit cubase to get out. what is going on?

Hi and welcome,

Most probably it’s on Kontakt side.
