Me and my collegues have Camtasia 9 now. I have a Mac, they have Windows. We export our files for each other (for mac/windows), but it doesn ́t work propper. They can open my project file (which I saved for Windows, but created on a mac), but Camtasia won ́t regognize my video, so there are only callouts. What ca we do to share and work on the same projects?
