aTV Flash 4.01

I've been using aTV for 4 years + now I think, Always worked great. When later versions came out, and my time expired I decided not to buy an extension as the software worked fine as it was, and I was in no need for any upgrades. Now my aTV restored to factory settings (some strange bug), so wanted to install the last file I had in my back-up. It does not let me back up, as it mentions it is not the latest version. Any help on how I can re-install 4.0.1 again on my ATV ? Angelo
