It's not that I don't believe you, but I'm not sure if it'd be that helpful. Like I said before, I purchased Adobe Flash Professional CS5.5 from JourneyEd rather than Adobe itself. When I mistakenly removed it, I don't believe I registered it.
I still have the e-mail with the download link (but no serial number); so if I try to set it up again, will I be able to register my product before being prompted to include the serial number?
