I did that too …
But I couldn’t solve the problem myself … 
Please help someone, @hi1 and me! 
You’ll need to provide more details. It’s not enough to just say that something happened to you, too.
Post a link to the project and explain which screen, button(s), label(s), etc. are not working as expected – and tell us what you expect to happen and what actually happens when you preview/live test/download the project.
Excuse me!
A few minutes ago, I accidentally deleted a project while working.
I haven’t made a copy so I can’t do anything anymore … 
I’m really sorry for your reply. 
really sorry… 
Sorry to hear that.
