Photoshop :: Deactivation Denied!

I'm not talking about the "deactivate" menu being greyed out or anything. I can select it and then tick the checkbox to erase my serial-number, but when clicking on "Deactivate" and answering with "Yes", it takes about 2-3 seconds before I get a "Deactivation denied" message. I tried to call Adobe Support, but the woman I got on the phone was completely useless. She didn't understand what I wanted to do, and wanted to provide me with new activation details. I explained to her three times why that wouldn't work and she simply skipped ahead to the next useless response in her database. Here is what I'm trying to do: 1) Deactivate the entire CS4 Master Suite.2) Make a backup of the my HD3) Clean-install Windows 7 RC (can't upgrade from Vista Business)4) Install and activate CS4 Master Suite on Windows 7. If that works (including my other important software) then I would continue using that machine until Windows 7 final is released in October and then I would need to repeat steps 1-4 again (you can't upgrade the RC to the full version). If that doesn't work (or one of my important programs doesn't work) then I would use the back-up and re-activate CS4. Why is there a limit for deactivations? I've activated/deactivated this serial number perhaps 2-3 times. Since I always deactivate before activating a new computer,
