Rusty, without actually seeing what is going on it's really hard to give you advise.
#1 you can not put on a shorter string... It doesn't work that way.
#2 you can get another module for that bow, or a cam, I am not sure.
#3 more than likely when the draw length was shorted, the peep stayed in the same place, and wasn't readjusted, it may be that all you need is to move your peep to the proper place.
With your eyes closed draw your bow back to full draw. Open your eyes your string should be at the tip of your nose, and your eye should be looking out your peep. If this is not happening, then the peep is off, or your draw length is wrong.
A Good bow shop should have made sure the bow fit you. Most bow shops will not just change the length without making sure that's what you need.
If you can take a picture of you with the bow fully drawn and post it, someone will be able to help you.
