Cannot create Ruby SDK version 1.0.13698

Just fresh installed IntelliJ IDEA 7.0.2 Build #7590 and plugin version 1.0.13698

Nothing happens when I try to add a Ruby SDK in the Project Setting page.
Get the below stack traces in the Intellij log. Also get the "main.rb file cannot be null" failure when I start Intellij up
Anyone have a work around? Can't do much without a Ruby SDK.
