Saving Issues

I am having major problems with saving work which is really bugging me. Whenever I edit a code on Robot Main.vi and save it, the code disappears when I close the project and reopen it. I clicked save everywhere even on the project explorer window, but it is still not working. Please help me with saving work!!

Never mind I realize what I was doing, I was overwriting the project every time and I was opening a new cRIO project. Pretty stupid of me actually.
