Problem exporting my UV Unwrap

I am trying to export my UV Unwrap so I can use it in Photoshop. Everytime I try to export the UV Unwrap it gives me a “image file path does not exist”. I tried hitting “new” and typed in a size of 1000 x 1000. Blender lets me export the UV Unwrap, but when I open the file in Photoshop it is completely black.

Any ideas?

what script/blender ver. are you using?
