Oh no! But, I maybe found help! Go to YouTube and type in Innovations Knitting Machine. There are a bunch of videos for this machine including knitting a flat panel. I'm not sure if there is help for the skipped stitches issue, but maybe.
You can also try other terms in a search like "Innovations knitting machine help" or "Innovations knitting machine cast off". Casting off is also called binding off so you could try both.
And don't forget that a flat panel of stockinette will curl. It needs a fairly wide border to help it.
