All files locked

Solution 1:

you may have inadvertently changed the ownership of those files to some other system user (root, or some such)

I'd usually fix this by opening up a terminal window and doing something like:

cd /home/ccrama/
sudo chown -R ccrama *

Be careful - you don't want to do this anywhere outside your home directory, as that can mess things up.

If you don't know what these commands do, typing "man " at the command line will open up the documentation for that command- like:

man chown
