HOW-TO create ID File for Domino Administrator

I uninstall and delete entire …/notes/data directory on my Windows machine. Now, with Domino Administrator and Notes re-installed, when Notes try to connect to Domino server, it asks for my UserID file, which apparently has been deleted. Since I was the only Administrator and no other Admin accounts in Domino Directory, without a backup ID file, how do I create/recover the Administrator ID file?

Thank you.
