I have a copy of Lr that I purchased from Amazon download. My PC had a non-recoverable failure. I have so far, been unable to reinstall lightroom on my new machine. I have a product code, and have downloaded the software, however I can't get it to recognize my product code. I do not have Lr installed on any other computer, and the license agreement states I can have two machines on the license.
What are the first four digits of the product code you are using?
The first four letters of the license key are LTRM. The license is for
*Adobe Photoshop Lightroom 5 Student and Teacher Edition - Win
I am faculty at UNC Chapel Hill. I verified with my initial purchase.
