It's time to start over.

First, start with the rest adjusted so the arrow is centered.
See the Easton Tuning guide for preliminary setup.

Once that is done, try again with paper to get the arrow leaving the bow properly. Make SMALL adjustments, and follow what the guide says. Keep in mind that a clearance problem where your fletching is making contact with something as it leaves the bow can mimic other problems.

When it looks good with paper, do some bareshaft tuning to get it really good, and then broadhead tune to get it humming with blades.

The people here can help you better if you list the specs of your setup.
Type of bow, release or fingers, bow draw length, arrow length, arrow type, point weight, etc. It can be pretty involved, adn the more somebody knows about what you've got, the better.
