I've wiped my iPad and would like to re-install a previously purchased app. I do not know which computer has been authorized to use the app so I cannot de-authorize one computer and authorize another. I use my App Store account both for personal and work purposes. The application that I wish to reinstall was purchased directly from the iPad at work using my personal account. But, the iPad was re-initialized without making a backup.
I have an iPad 16G Wi-Fi, iOS 3.2.2.
