Been using CC but in my account is says the plan is not activated on any device.

I'm on a MAC, using the Adobe CC for photographers....Photoshop and Lightroom.  The other day I accidentally closed the Adobe CC icon at the top right of my screen...which may be the problem....removing it from my screen.  Today I had to go into my acct to update my credit card info and I noticed that the account says my plan is NOT activated on any device.

I need to know the easiest way to make sure my plan is activated (so far only on my desktop) and to get the Adobe icon back.

Can someone help?

Thanks
