Hey!
i had the same problem and really freaked out cause i had a lot of sensitive data in the locked folder..

..then i found this really good site that showed me how to fix it..

Here's what you need to do :

1. Go to the directory where your folder is in.
2. Create a new notepad file and paste this without the double quotes:

"ren Users.{21EC2020-3AEA-1069-A2DD-08002B30309D} Users"

(Make sure to replace the word “Users” with the name of your folder.)

5. In Notepad, go to File -> Save As, and save it with the name "key.bat" (MAKE SURE TO CHANGE THE FILE TYPE FROM .txt to ALL FILES)

6. Run the "key.bat" file

Your folder should work now.
