Hmmm... I have no idea what could be happening, are you sure your casting on the right amount? I just cast on 110 (had to count 4 times though, kept counting wrong, that's the reason I ask if your co the right amount), and did the first row, and I had 110 at the end of it, so I'm not sure where you might be going wrong.
I almost forgot the last yo at the end before the K1 too, but like I said, I'm not sure where you are going wrong. Terribly frustrating for you.
