Netbeans .form instead of GUI editor

I 开发者_开发百科have a netbeans project in 7.0.1 and I have been using the GUI editor that is built in. It was working great! However this morning when I opened up the project instead of showing in the GUI editor it shows FILENAME.form

I was wondering if anyone knew how to get the project back to using the GUI editor instead of the source .form files.

Chack that the "GUI Builder" plugin is both Installed and Activated.
