installing Photoshop CC on 2nd computer as trial version?

Hello,

I've installed CC on my macbook pro (currently have it installed on my iMac) and when I install Photoshop and open it,

it asks me to sign in for a trial version? and says i can continue to use photoshop after trial period by purchasing

the software.

ideas anyone?

really can't understand as I'm 4 months into my 12 month subscription.

Cheers
