That sucks, I was just reading up on bowtechs warranty. As long as the malfunction wasn't your fault I believe your bow should be covered by their warranty.
From Bowtech's Website...
Q: Does my bow have a warranty?
A: All BowTech bows not sold over the internet come with a non-transferable lifetime warranty to the registered original owner. This warranty protects against any failures of the product due to defects in material or workmanship, and does not include any damage due to abuse, misuse or modifications to the bow’s design. The following exclusions apply:
* Cable slide, cable and strings, hush kit, bearings, paint and/or hydrographic film transferred finishes.
* Damage caused by abuse, mishandling, dry-firing, alteration or modification to original product.
* Other excluded damages are those resulting from either loose mod screws or shooting arrows less the five grains per pound of draw weight.
The BowTech Warranty covers product purchased from Authorized BowTech Dealers. BowTech products purchased through the internet are not warrantied.
Take it back to the dealer you bought it from and they should be able to help you deal with bowtech.
