Can't upgrade from Flash CS4 to CS5

[Guest]

I have Flash CS4 and bought an upgrade to CS5. When installing, it says: "can't find the qualifying product". I specify that the qualifying product is Flash CS4 Professional and write its serial number. It won't accept the serial number.

Hello again,

I got a chat window with a support representative. The connection disappeared somehow... How can I start a new chat?
