Raix:ui-dropped-event Error: ENOENT on Windows7 x64?

When trying to add raix:ui-dropped-event to a brand new Meteor project on Meteor v1.4.1.1 I am getting the following error. Does anyone know what it means? I am on Windows 7 x64. Thanks.

meteor add raix:ui-dropped-event
      throw error;

Error: ENOENT: no such file or directory, open 'C:\Users\Josh\AppData\Local\Temp\mt-jlfvl6\os\packages\raix_ui-dropped-event.js.map'
    at Error (native)

Very weird.
I created a brand new project with old v1.4.0.1 version of meteor and it was able to successfully add the package. Then when I went back to my project I could add the package then.
