Hi I just bought an Adobe photoshop lightroom 5 from amazon. It just came in the mail, and I am trying to install it. What I am having problem is the serial number. As I put the serial number in it says that this is an updated serial number and it needs the previous serial number. I don't have that because this is the first light room I have.
You purchased the wrong license. You should have purchased Lightroom at the full price. I don't know what the Amazon price is, but Adobe sells it for $149. You will have to contact Amazon and see if there is any way you can exchange for the right license.
