antrouter r1-ltc

I have 2 antrouter r1-ltc setup and going. One gives me a hash rate on the site and is going the other one which I connected first is saying no valid shares yet. The second one I setup set itself to a difficulty of 32,768 dynamically but the first one I setup set itself to difficulty of 65,536 dynamically. Would that make a difference? If so how would I go about fixing this and getting that one to start going?
