Motion 5.2 failed to download even from purchase window
I'm given an option to update to Motion 5.2 from the app store, but it fails with this message: Motion failed to download go to the purchases window...
Same message comes up when trying to update from there.
I trashed Motion then restarted and tried again, but same message comes up: Motion failed to download!
I am on OS 10.10.3
Could someone please assist with this?
Mac Pro, Motion 5.2 update - OS 10.10.3
