Recently I've deleted all the downloaded apps from my iPad at my iTunes Media folder (yes, it was a mistake, but anyway). Today I've backed up my iPad, upgraded it, but there has been an error so I wanted to restore my iPad from backup. It restored, but then it tried to transfer my apps (IPA files) from my iTunes library, and complained about missing files. How can I force apps to download on iPad, or how can I force iTunes to check for existance of files and download if needed? I've tried Consolidate Files but nothing happened.
