So I put a fresh battery in and nothing. Thought maybe I put it in wrong but that wasn't it. Put a different battery in, still nothing. Figured maybe my carto was bad so I tried a new one and nothing. Tried cleaning it all and still nothing. Any ideas? Could I have two cartos in a row bad? The first one worked for maybe a second before quitting which wad odd to me but now I'm just lost. Someone help please!
