Here is what some people said on Archery Talk:

Your bow is fine but most likely needs to be worked on a little. The string needs some twist in it. It is over rotated which allows the cable post to push the cable out of it's track. I always build and replace the strings on the airbornes 1/4" shorter. The factory strings are twisted a lot already but can handle several more twist if you pursue my suggestion. Add about 12-15 twist in the string.
I like this idea. What do you guys think?

Chances are the bow will be alright, but you really need to have it checked out!
More than likely, as you were letting down on the bow you torqued the bow in your hands which caused the string to ride up the sides of the cam grove, thus causing the string to slip off the cam.
Good luck with the bow!
I hope he is right. Everybody else said something to this effect.
