iMovie will not update to the latest version
I currently have iMovie '09 (8.0.6) installed on my iMac running OS X Mavericks. While I have been able to upgrade all of my other iLife and iWork apps, I am prompted to purchase iMovie from the Mac App Store (instead of the button reading 'Free' or 'Update'). This is despite the offer to provide existing users of the software a free upgrade to the latest versions. Apple has not responded to my email requesting support. Has anyone got any suggestions to help me resolve this?
