Is my cgminer (scrypt) working / Mining on middlecoin pool
I think your main issue is that your hash rate (speed, essentially) is extremely low. You're averaging about 3Kh/s. For comparison, most mid-range miners are running around 5-600Kh/s, and if you run a mining tool on your Google Nexus 7 tablet or Nexus 4 cell phone you can get around 2Kh/s which is very close to what you're getting.

I can't really help you with this without knowing what kind of hardware you have that you're trying to run this on, but take your video card model and search google for "cgminer settings" with your model after that to see what you can find.
