I can't edit my paper on word. Everytime I type something on my paper, it
won't let me...it says "This modification is not allowed because selection is
locked." I tried trying to click on the Protect Document icon but I can't
even click on that. I've tried everything I can think of and nothing seems
to work. Please if anyone knows the solution to this please let me know as
soon as possible. Thanks!
