You just had a limb delaminate. No big deal except for the timing for you. Happens all the time to all makes and models.
If you bought it new and are the original owner then it will be covered under warranty except for the shops labor. If you get it in to a Mathews dealer quick it takes about 10 days to get limbs to the shop from Mathews assuming that the shop would order them that day. They will not be camo though... they will be matte black.
The serial number is located on the back side of the riser right up under the bottom limb pocket.
