Does anyone know why Adobe don't recognise the student edition of Photoshop when it comes to moving on with the product. I was hoping to subscribe to the Photoshop and Lightroom CC offering, but the edition of Photoshop I purchased doesn't qualify.
"Why" can be a deep question that might not help you. In this case it most likely has to do with Adobe marketing strategy, and you probably don't want to know why, really.
Rather, why not call Adobe and discuss it with them?
