How to Activate InstallShield 2009

[junppplus]

I bought a product by other shops, so I registered my product code.

Then, I tryed to activate my InstallShield but I couldn't.

I receive the message "Serial Number Not Registered" through I registered my

product code. So, I visited register site again, I tryed to register my code

but the web site answered "This serial number has already been registered."

So, how to activate InstallShield 2009?
