Can anybody tell me why when I try to connect to supernova through the etherminer it closes automatically?

I have the .bat set to ""bin\ethminer.exe" -G -F stratum+tcp://soil.suprnova.cc:2000 -u Weblogin.Worker -p Worker Password"

Do I have the mining pool settings wrong? I'm using windows 7 64 bit soilcoin mining package with a regular .bat file.
