Just select N/A for the top and try it again. A lot of people here really hate auto routing and don't like Eagle but I have not had problems with it at all. You do have to spend some time setting up the rules and there are tricks that help like route single side first the add the 2nd side and route again or build your schematic with critical parts first, auto route then add the rest of the parts and again auto route. Parts placement and orientation had a lot to do with the success. I do clean things up after a auto route but I have great luck auto routing and wont go back to the manual way if I can help it. Plus the price is right.
