unable to enter the serial number because it is alphanumeric.
My Windows 8.1 computer died so I was forced to purchase a windows 10 computer. I have successfully installed the Photoshop 5.5 that I purchased. It runs perfectly as a trial but I am unable to enter the serial number because it is alphanumeric. It is a legit serial number that I paid for. How do I get it to work? There is no phone support and no help in support.
