I have been having an issue relating to photoshop cs5. Originally I purchased a copy of CS5 extended and loaded it onto my computer - no dramas there. Since then I undertook a course that required Illustrator as well. I then had to purchased Adobe Creative Suite that contained Photoshop, Illustrator and InDesign. I loaded that onto my computer and hadn't noticed until tonight that my copy of Photoshop is no longer the Extended version. I have been shooting some short film type stuff and wanted to edit it but unless I have PS Extended I can't. I've uninstalled PS from the computer and then reinstalled the PS CS5 Extended disc but I still only get the standard version coming up. What am I doing wrong?? I don't want to have to fork out for video editing software after I've already paid for it once. Can anyone suggest what I might need to do?

Cheers
