My serial number of Design Premium CS5.5 is not recognized for the PS, after that I have re-installed the program. How can I solve this problem?

After that I upgraded my Mac OS to 10.10, PhotoShop was no more working. The rest of the Adobe design Premium CS5.5 programms were still working. To resolve this problem, I have re-installed PS now it works, but only in the trial serial number of "Adobe design Premium CS5.5 ' is not valid. No idea how to solve this problem. Adobe customer service can't help. When I installed Adobe design Premium CS5.5, initially, I had the same problem with Acrobat ProX; to make it work, Adobe had to provide me with a number of additional series for this program.
