Power Point cant activate some controls???

Hello All!!

I was wondering if any Power Point wizards out there could help me,

Im trying to open a Powerpoint that has some fancy pancys flashy marcos and stuff but unforchantly it comes up with this message " Some controls on this Presentation can't be activated. They might not be registered on this computer" which I dont have a clue what that's supposed to mean :p

if it helps im using Ms 2007 on Windows 7

Also i have tried reinstalling Abode Flash

if anyone could help me that would be great :D

Thank you
