What name does the conf file need? I tried hodl.conf, hodlcoin.conf and HOdlcoin.conf but can't get the miner to connect to the wallet...

hodlcoin.conf:
server=1
rpcuser=xxx
rpcpassword=xxx
rpcallowip=127.0.0.1
rpcport=8332
miner.bat:
hodlminer.exe -a hodl -o http://172.0.0.1:8332 -u xxx -p xxx
Should work, right? Maybe it is because when I installed I set the data directory to a different hard disk?
