Cuba studio trial premium subscription problem

Dear sirs,
i activated the trial subscription two days ago for the cuba studio 2019.1 IntelliJ edition, now I have done the last update and immediately appeared the trial expired subscription message:
"Your CUBA Studio trial subscription has expired and Studio has switched to the free mode.
You can purchase subscription at CUBA Store to continue using premium features. "

How i can solve this probelem?

Thanks and regards


Please attach screenshot of the CUBA -> Subscription Information window

i have this message:Clipboard-1

After restart again cuba platform on Subscription Information window seems to have re-set to a valid subscription trial date, precisely 2019/11/20:

even if i’ve activated the trial subscription exactly the 28/10/2019.

Thanks and regards
