When I click on Time Machine, I just get a space-image with multiple Finder windows on top of one another. I don't get anything that actually lets me select anything. I think it used to really clearly just give me an option of backing up. Can anyone tell me how to fix it? This should hopefully be a screenshot It looks to me like it says my last backup was Oct 2011 (ah!) I should add that I yesterday reformatted the external drive.
