Download it with your laptop or desktop. It doesn't download with iPad.

Have you tryied to take a look at the iCloud settings to see if you have contacts enabled? Also you can check out the mail settings to see if u have enabled it there too. If nothing don't work, the only way is to restore your phone and load back up your content via iCloud.

I can download it using my laptop

iCloud has a nasty habit of deleting the previous backup every time it does a backup. If you really have an old backup intact, there is a way to restore from it. I forget the procedure, but I'm sure you can Google it. It's a good idea to manually go into your backup directory and manually copy it over to a new name once in a while. That way iCloud won't touch it, and you can use it in an emergency such as yours.

Here's a website that describes how to do it:
