I downloaded trial version of PS CC and then subscribed to the cloud package including PS and Lr. I cannot open PS, just keep telling me that trial has expired. Any suggetions?

Can any one help?

I have subscribed to the cloud package including Ps and Lr after previously downloading the Ps CC trial.

Cannot open up a newly downloaded Ps, just keeps saying that my trial has expired.

I have looked online for help but just keep going around in circles.
