Thank you for your reply.
Where do you download the additional content?
I also have an additional problem. In the App Store and in the PURCHASED page, I accidently deleted the Final Cut Pro X purchases.
I then went to the App store and tried to download FCPX again. The download button shows INSTALLED. I click on it and nothing happened. I also put FCPX in the trash hoping this might work.
I option -> clicked and control -> clicked. This did not work.
Any suggestions to these problems?
