GWT designer in Eclipse Juno

Hey everybody. I'm having a problem creating a new GWT User Interface with window builder in Eclipse Juno. I followed the installation instructions and still  get a popup window that says I've got to load additional WindowBuilder toolkits everytime I try to create a new project. I click finish to install the toolikit as it suggests, and it shows the tools I've already successfully downloaded and a Google Plugin for Eclipse 3.7. Am I missing something? I didn't encounter any issues during the installation, and everything is up to date, so what is it?
