I have Lightroom 5 on my laptop, but I want to use it on my new iMac. I downloaded the same version onto my iMac and now when I am trying to input my serial number (from my laptop), the last 4 digits are only showing up like : 'xxxx'....... it's gi showing me the first 20 digits of the serial number, but not the last 4. Why? Help please!
You might also want to keep better track of your serial numbers in the future, either writing them down or putting them into a text file that you can find easily.
Once again, I should have looked into it further before posting. Went through my emails and found it in there from when I first purchased it.
