SketchUCam HELP!

Hey everyone, for some reason I am having all kids of trouble generating the G code for this park using sketch U cam. I have been following marks tutorial and its just not working at all. I am unable to select inside and out side cuts for this part. I have expanded and flattened just like I am supposed to. Any help would be greatly appreciated!

Thanks.

P.S I have attached the file I am working on.
