The serving wear is a nature of the beast with single cam bows. No need to panic. On the factory made strings and cables the serving is not that tight. If you take your bow in and have the wear areas of your string and cable reserved, I would be willing to bet your problem will go away. I had this same thing happen to my bow. After having my lesssons done on manufactured strings and cables vs hand made and having the work done on my bow, I haven't had a problem since.
