I'm having trouble getting started with mining. I've decided to join the dogemoon pool, following these instructions, but I can't seem to mine using CPUminer. I have this added on as the target...
C:\Users\USERNAME\Downloads\pooler-cpuminer-2.3.2-win64\minerd.exe --scrypt -o stratum+tcp://mint.dogemoon.com:3333 -u WEBLOGIN.WORKER -p PASSWORD
...but it closes instantly, and says it doesn't recognize the '--scrypt' command.

I tried CGMiner as well, using the same method, but it had the same response about not recognizing '--scrypt'.
Now I've moved on to BFGminer, using the Stratum method. It connects, but doesn't find any devices. How do I make it use my CPU? I have an AMD Phenom II N970 Quad-Core Processor, if that helps any.

Thanks in advance.
