I have bought a student CS6 as I attend Grays Harbor College in Aberdeen, WA and have installed it on my desktop and on my laptop, which I carry to school. The laptop and desktop were initialized with the proper number sent by email with no problems. Last Saturday when opening the program it wanted to give me a 30 day trial which is wrong, but I had to day yes and expected to put the initialized number in later. Trying to put the number in it says that it is not correct and now I can’t open the program at all.
I can understand that you want to stop the stealing of your programs, but penalizing the legitimate buyer is making it a little too hard.
As Jeff said, something is messing with your licensing system. Either it's a genuine permission issue or another software on your system is interfering, which could be anything from an overly keen virus scanner to some exotic freeware program that has replaced a critical system DLL. Anyway, you did provide zero system information, so this is not even beginning to go anywhere. Check the things I mentioned and then come back with more details.
