I have had this problem making a project (NO SPOILERS HERE) that goes like this: I try to share it online, with my CORRECT Username and password, and it said FAILED: INVALID USER, i mean What the heck is up with that crud!? SRSLY! >:-( :-@

Hmm... often when you get that error, you might want to try retyping your password into a text editor, check that it's all correct, then copy it, and paste it into the password box using "Control+V"
If that doesn't work, you could try going to your "My Stuff" page, and changing the password to something different, then try uploading with the new password

I also keep getting "Invalid User". It's a really short, simple program I wanted to share to someone that doesn't know about Scratch. I've tried "My Stuff" and redoing my passwords and all of that, but it's just invalid user. Uggh.

Are you sure you're capitalising your username/password correctly?
