OK. I think this means that the One-Click Installer thinks that you have no currently valid one-click installs.
I'm not entirely positive how they find valid installs, but I do know that when you perform any manual shenanigans like moving your install from one domain to another or move it to a different location under your web directory, you invalidate the one-click install and have to resort to manual updates thereafter. I've heard these updates are relatively painless.
Did anything like this happen with your one-click install of WordPress?
