Once you have your edits complete then you have to go TOOLS and choose Compile. Next go to FILE and select EXPORT then select Memory Card Format File,
Then select your Memory Card for the place to save the file to. Also make sure that only the file you want to load into the controller is the only file on the card.

Thank you very much. Exporting for memory card was the step i was missing.
