A friend and I was shooting and noticed his string was fraying, so that ended our shoot. he ordered a new string we got it all put together and started tuning the bow and noticed his string is fraying again.
we started checking it and noticed the the string is aparently hitting the cable slide rod as that is exactly whear the fraying is at. it is an older bow and been used for many years without any problems.

any ideas on how to fix this issue?
