Sorry you are having trouble! There are 2 reasons this could be happening, and fortunately they are both really easy to fix 🙂

1) You actually downloaded 3.0, but the activation window still says 2.1 – This is a jsut a bug where we forgot to rename the window (Whoops!) you can check what version you actually have by going to NetNewsWire > About NetNewsWire

2) You may have an old copy of the download stuck in a cache or a proxy somewhere. To get around this we’ll throw a fake argument at the end of the url to force your browser to download from the source 😉 Try this:
