help save logic

guys then I need help by mistake instead of saving the project I pressed the cross in the upper left to close and I remain in the screen I'm plug in that I was using.

he tells me if I want to save, I tell him to save himself.

when I open the project instead of showing me the entire project on the screen you only see the plug in but if the space bar is down the song goes in loop

.

I need help is an important project can someone help me?

sorry words but I used translate google
