May be relevant. I saw this comment in "official" v5 sgminer thread:
Cgwatcher is driving me crazy! Why I can't use it with the new miner? It's overiding my settings and creates ckolivas bin instead the darkcoin bin..
I constantly had the same issue. No matter how well I did my conf file to point to the right kernel, it always used ckolivas somehow. But always tried with Cgwatcher only, never run the stuff from cmd prompt. I am now rented out for the whole day, but suchmoon this could also help you out although you never stated your type of problem with v5.
