Mac OS X is a multi-user operating system with the concept of file owners and file permissions. If another user created a file, it's possible that the new account does not have permissions. Check the "Get Info" dialog of your files at the bottom. If it doesn't say "You can read and write" you need to change the permissions (enable that part of the dialog via the lock icon).
