I bought new copies of PK Sharpener, PK Color, and PK, for my new Mac Pro, running 10.10.1. I have all these products on other machines with earlier operating systems.
When I downloaded and installed and entered the serial numbers, I was told to "enter the numbers exactly as shown....etc.". I did this repeatedly, until I got the message that the serial number was wrong. But I correctly entered was what was sent. Only 1 of the three serial numbers (for Photokit, but not for the other two) was accepted to activate.
I've sent a message to Pixel Genius, but if anyone else has had this problem and knows a solution, I'd be grateful.
Thanks,
