Activation

"Type 'Agent' in the chat box to bypass the chatbot and be connected to a person."

That's what I tried to do. But (after a very long wait) eventually the agent in whatever country gave me a copy-and-paste response that they're not allowed to answer my question because that would constitute providing assistance for a defunct product. They suggested I post here instead.

It's for Premiere Pro CS3. Evidently customer service will only answer questions about the subscription versions that you pay them for for life instead of buying once.

When I try to register my Premiere Pro on my new computer it blocks me. (No error message; it just keeps sending me back to the page to enter the serial number.) I assume it's because I already registered it to the maximum number of computers in the past. I'm willing to deactivate it from an old computer so I can use it on a new one, but in my account it claims that there are no Adobe products registered to my email address (which makes no sense, since it's the same email address I've used for as long as I've had an Adobe account.

So I can't activate it because it's already activated on too many computers, and I can't deactivate it because I don't have it activated anywhere.
