Automation is recording for Orange Tree Plug-in...

Hi. Whenever I activate a controller in the Orange Tree samples plug-in in Kontakt 5 in Cubase, the automation won’t record.
Whenever I replay the sequenced guitar track, the whole step guitar slide in that I’ve just controlled during automation record wont play back because it hasn’t recorded. Even after I’ve clicked on Automation record nothing is working.
Please help.
