start up code composer, you should see 'import project', click on that and use browse from the window that opens and go to your 'electronic-leadscrew-1.3.01' folder, open it and highlight the 'els-f280049c' folder and then click finish if your project has appeared in the window.
That should get your ELS code into composer. If you need further help ask in this thread as others have got a lot further than I have. 
Best of luck
