Ricky,
You say you drilled a hole out from the end of the crack, bbut did you also pop a mini-bullseye in the drilled hole? This is important because the mini forms a cone down to the laminate, so that when you push the crack, it will run into the bullseye and stop there, the pressure being relieved by the bullseye and drilled hole. This is one of those things that requires a lot of practice. Get you a scrap windshield and practice all phases of the proceedure, drilling, popping the mini, forcing the crack into the bullseye, and repairing cracks. Pay attention to what you are doing each time, so you can recognize your mistakes and hopefully not repeat them, and also recognize your successes and build on them to gain confidence and skill.
I agree also with the other advice. Contact the maker of your equipment and get advice from them on their recommendations for crack repairs. The main thing is to practice, practice, practice.
