do i do? plz help

Hi ogiejoe

Is this a trial version of fcp x? What happens when you go to app store? Do you see fcp x in the updates section? Is it updating in the "background"?

Are you using the same account you originally purchased FCP X from?

Check the Purchases page of the App Store to make sure the application is listed there.

Ogiejoe, Welcome to the forums.

Go to the App Store using the same account that you purchased FCPX originally. You may need to login with your password.
If you go to the "Purchased" section by clicking on the icon on the top of the page and you see that it says the application is "Installed" and the "Download" icon is not available or greyed out, then try using the "Option" key held down while clicking. It should redownload. If it doesn't try re-clicking the "Purchased" icon while holding down the "Option" key. This should allow you to re-install.
If all of this fails, make a back-up of FCPX data and then un-install FCPX before trying again.

If you are on the latest version of Yosemite, then FCPX gets updated to 10.2.1. It is possible that this caused a glitch.

There is no charge for downloading previous purchases, and FCPX is supposed to not lose any data with a re-install of the app. Always a GREAT idea to have multiple back-ups.

You can also install any app you purchased from the App Store for any/all computers you own, as long as they are linked to the same account.

Hope this helps, Greg

Wao! ok as you have explained i think its exactly what happened to me because i didn't sign in with the Apple ID used in purchasing fcpx. i will do that and give you feed back. i appreciate your reply. thank you very much.
