Hi there,

1.First thing you want to do is to open an another project scene(eg. Angrybots scene or boot camp scene). Then it should automaticallly open up.

2.You can remove temp files and other files execpt Assets (i dont know about keeping the library folder i have not tested with keeping it yet).Then open your seene it should open up
