Backing up save data problem?

I went to go back up my Saved data and the games I usually back up (Borderlands, Modern Warfare 2 ect.) the copy button is gray and it won't let me? Is this happening to any one else?

Games I have been backing up before are now doing this. Borderlands and Modern Warfare 2 I backed up all the time, now it is gray.
