cannot update imovie
I tried many times to update the imovie 10.0.9, which my mac already updated to OSX 10.10.4
when i type the apple id with password, it keep saying that wrong password or wrong id...
so i keep forgot password then reset... but no matter how many times i used different apple id..
it shown:
This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled.
please help.. what should I do ?
thx!
iMac, OS X Yosemite (10.10.4)
