Licence "error"


I am experiencing a problem with Adobe Flash CS3.It was working great till today.I uninstalled and re-installed Flash Player 9 because I was having some problems.But now,when I am trying to run Flash CS3 the Licence window pops and the buttons doesn’t respawn,I can only close it by hitting Alt+F4.Here’s a [screenshot]
Any suggestions?
Re-installing the program won’t work,because when I try to do so,I get an error(like in all CS3 programs)

Thanks in advance,
