If you are not able to use Photoshop cc now, be sure that you are signed in with right email address in the application, under which you have purchased Subscription.
As i have checked your email that you have registered on forums support, I Couldn't find any subscription for Photoshop CC under this email.
you may also see the links below, that might help you-
I have tried the links, but it was not succesfull.
Now I do not know what to do!
I have a propose:
I open a new contract for one year (till november 2016) with Photoshop CC 2015 and Lightroom CC 2015 (not test version)
I pay about € 12.
After I have open the new contract you close the old contract (so I pay not 2 x € 12)
You may please check personal message. I have just sent to you.
Now was it succesfull.
It was the other emailaddress.
Now I can work with Photoshop CC and Lightroom CC.
