The reason you were not asked to activate the 727 again is because the Windows Registry entry for the 727 is still there. Try doing a "Repair". Run the installer (use the "Run as administrator" option if you are using Vista/Win7/Win8) and select "Repair" when given the choice to "Repair" or "Remove" it. After it finishes, start FSX and test it to see if it's working correctly.
If you are still unable to work the buttons, you should try a full uninstall/reinstall (KB #685), which includes deleting the 727 entry from the registry (see image below). Check-in to Your Profile > Product > Customer Support > Search KB or Submit New Ticket, search for KB #685 (without the #) and follow the instructions.
This image shows the registry entry for the 727-100 Base Pack (721PRO_FSX), as seen in my Windows 7 64bit registry.
Directly below that, is the entries for the -200 (722_FSX) and the Freighters (727F_FSX), in case you need to remove them as well.
