I cant download hd cinema on my ipad it keeps saying cant dowload at this time and i already

Hello judychang,

Thanks for contributing to the Apple Support Communities.

It sounds like an item from the iTunes Store can't be downloaded on your iPad.

Try these steps next to resume the download:

If your download was interrupted using your iPhone, iPad, or iPod touch

1. From the Home screen, tap the iTunes app.
2. For iPhone or iPod touch, tap More > Downloads. For iPad, tap Downloads.
3. Enter your account name and password if prompted.
4. Tap the blue download arrow to resume.

If you can't complete the download on your iOS device, you can download it in iTunes on your Mac or PC and then sync it to your iOS device. You can also transfer purchases from your iPhone, iPad, or iPod to a computer.
