rpcport=44101
I was starting the Ultracoin wallet .... then would go to the debug and do that command setgenerate true, then starting my bat file.
edit *** we didn't need to start the qt wallet with the -server command like other coins did we? ****
the port doesn't have to be specified in the .conf, if that port # is wrong, that might be a problem, i don't know what the correct port is as i didn't include that in my .conf
the setgenerate true is for wallet mining, it isn't need for gpu mining, i have no idea if that could cause a problem, but i didn't wallet mine while mine was working
the QT wallet has to be open/running to solo mine, but you don't have to start it a special way
if you have a strict firewall, did you check its log? if you are doing the gpu miner on the same computer as the wallet this isn't likely to be a problem, but just throwing it out there just in case
good luck
