It sounds like you have been using a 30 day free trial. If so, apparently your 30 days have elapsed.
Will check, but took out the subscription to Ps And Lr months ago with an update to Lrcc 46days ago I take it that it was included in the subscription?
Everything else seems OK.
Have you tried
click Edit>Preferences. Under the Performance tab, uncheck Use Graphics Processor.
Many thanks John.
I have just unchecked it and all seems OK.
