Cannot use PhotoShop CS6 after trial expired, even after purchasing Creative Cloud Student Edition

Hi.

I had PhotoShop CS6 trial, which expired.

I have purchased Creative Cloud student edition, I receive a message that my PhotoShop trial has expired.

I am prompted to purchase the product to extend it, or type in the product's serial number

(I never received a serial number.)

I paid for Creative Cloud and have an order number, I should not be having this issue. 

I have uninstalled and reinstalled PhotoShop CS6 multiple times, I also use DreamWeaver and am fearful that I will encounter the same issue. How can I use the Photoshop CS6 after I have paid for it?
