Well - don't go throwing the baby out with the bathwater just yet, Essie.

Sure - it sounds like you're not getting the "power shaft" (on the back of the pasta roller attachment) properly aligned with the "hub socket" (in the K5A).
Try this ....
1. Unscrew the "attachment knob" all the way (so it doesn't obstruct the shaft of the power hub).
2. Insert the end of the pasta roller attachment into the hub and twist it around until it slips into the mating opening ... the square peg fits into the square hole ... and then rotate until it is upright and the allignment pin on the back of the attachment fits into the notch on the hub - by the attachment knob. It should then slip all of the way into the socket.
3. Now tighten the attachment screw and try it.
It really sounds like you just didn't get everything lined up right. A little "wiggle and jiggle" might be all it needs. I really can not think of anything else that would be wrong with any model of KA.
