I have wasted weeks on working on a project in Delmia Shop Floor Machining. Everytime I  have completed all my toolpaths, saving as I go, just to close the app for the night. The next morning I can never find my work. All I find is the physical product that opens in Product Structure Design which contains none of my previous toolpaths that I have created. How do I open and continue work from previous Manufacturing Cells that contains full data.

Thanks for any help
