VS 2010 All Control disappeared suddenly

In the project I'm working on, I was editing a splash screen and when I got done, I clicked save all. I moved on to my main form's designer. When it came up, all controls I have on the form was blank. There used to be a ton of controls in it, so I am extremely confused about where everything went.

I tried close + reopen, restart computer, nothing seems to work.

I checked the properties window and it thinks everything is still there:


But in my form, it's empty :cry:


This is the screenshot before


Please help
