I just purchased Adobe CS3 Master Collection and it came (of course)  
with a serial key.  
I’ve installed the whole package with one serial key I’ve typed in before  
installing.

But now, if I open one of the programs (like Flash) I get a trial version  
pop-up which says I have to activate my serial key. When I click activate,  
the serial key suddenly isn’t valid anymore. What did I do wrong?

Please help me!
