How many projects did you have before?

You may have been hacked. Change your password first thing.

Do you think you were hacked? If so, change your password IMMEDIATELY. You may want to contact the scratch team by using “Contact Us” at the bottom of each Scratch page.

EDIT: Ninja'd. :P

my mom thingks it was a acident but it isint

Is your account used by many people? Or is it just yourself who owns it?

Do you notice anything different besides the projects? Also try looking in your trash, they might be there (link to your trash).

Scratch is very secure, so it's unlikely you got hacked. However, if you did, it was most likely someone that you know. Do you share an account? Have you told anyone your password? Do you log out of Scratch when using it at school? Do log out, and don't share your password. The hacker could be an annoying sibling, a close friend, or a classmate.
For now, change your password and use Contact Us to talk to the ST. They might be able to help you recover your project.

Yup, exactly. @Kittenlover64, I went on your profile and saw that your “About Me” described two people, so I was thinking your account must've been used by you and a friend. It's possible that your friend was the one who “hacked”.
