Script Is Gone

Hi,

I wrote a script for my robot to control its arm / manipulator. I saved the script in the editor and the project too and loaded it again today and the script control is not there anymore and I can not seem to find the script. Where are EZ-Scripts saved when the save button in the editor is clicked and how do I load a script? It would be really annoying if I had to write it all again...

Thanks for your help!
