Had this problem many times as a sysadmin, and calling Adobe is the only way to fix this. they can deauth your machines so that you can reinstall. Just as long as you have the serial/registration info handy. Even then you can give them a sob story and it usually works. Same goes for Microsoft and activation problems. Change too much equipment in your PC and MS thinks its a new PC. give em a call and they fix it quick.
