Jedi is looking to get a virus I see.Sounds like what came installed was their "subscription" based office where you never own the software you just rent it yearly.
The download you bought was it their subscription based? Or does it say an actual product name. The concern with the download is that MS at some point in the future can just discontinue hosting that file/version and force you to buy their latest version since the software won't be available for download anymore.
jedi is still running MS Office 2000 via physcial disc for this exact reason.
