Installation problems w/ new web android market

So I'm using the new web-based Android Market (market.android.com) where you can log in, select an app to install, select your device, and it instantly pushes the app to your phone where it automatically downloads and installs... or so in theory

I had no trouble logging in, no trouble selecting an app to download, and no trouble actually having it download to my phone.

However, once the app downloaded, it would just disappear, and would not install

It would hit 100% on the download, and then instead of going to "Installing" in the drop-down notification, it just would disappear. It gives me NO sort of error warning or message. It just downloads it and then disappears, as if nothing had happened.

Has anyone else had this problem? Are there any fixes to it? I'm hoping its just a problem on Google's end, considering this feature is brand spankin' new as of less than 12 hrs ago.
