I provided them with my emails and even my mothers email as I thought perhaps she purchased it (I can't remember). It might have been through Apple, maybe Best Buy, perhaps through the University I go to. I can't even remember where I purchased it. The problem that now arises is I don't have the box/disk that I got or whatever it was when I originally purchased the software because it was purchased years ago.

Apparently, according to customer service, the serial number that THEIR software provided me is not actually a serial number (WTF?!?). Now I can't use Photoshop on my macbook pro OR my surface pro 4. When trying to activate it on my Surface Pro 4, it appears to be missing 4 digits.

I copied and pasted all of the information to a word document, and then deactivated Photoshop on my macbook pro. I found what I thought was the serial number under 'Help' > 'System Info.' and then scrolling down until I found 'Serial Number: XXXXXXXXXXXXXXXXXXXX' I bought a Surface Pro 4 and would like to install it on there. I have photoshop CS5.1 installed on my old macbook pro.
