I've lost my projects is there any way to get them back

I've lost all my projects which I need for coursework and I really need them back. Is there any way to do this?



You say you lost ALL of your projects?  Could you have signed in with a different address?



No I've stayed on the same PC all the time I've been using app inventor.



So, they were there one day and the next, completely gone?  How many projects did you lose and what are their names please?



I had around 7 and I can remember there was one called Nightclubcounter, paintpot, magic8ball, space invaders. I cant remember any more.
