The mean surface temperature for such a planet is 278.302 K (about ten degrees cooler than Earth), still high enough to maintain water as a liquid.
This orbit is also well away from the orbits of the three other stars in the system, so there should not be a problem in that respect.
The relatively low metallicity (56.23% of Sol) favors the formation of a few lower-mass planets in the system, though there will probably be no more than one SubJovian as the most massive world.

This popped up while I was constructing my mammoth reply...
What figure are you using for luminosities? http://arxiv.org/abs/1504.07065 gives temperatures, masses, and radii, which should allow calculating that, but I don't know how to derive them for the contact binary, since it only gives a common temperature for the two.
Do you have any additional information on orbit parameters or the like?
