I've searched all over the net, but can't find any Flight/Payload/Fuel Planner (in one piece) compatible with and importable to CS 767/757 FMS.

Any ideas?  

PS. I find lots of alternatives for other 767's.
I've noticed, however, that developers claim that CS folks use a code that is tough to deal with....also they get no respond from CS.

I am not aware of any addons that would perform all three functions at once and send them to or have the info imported to the FMS. As you can see from my signature I use vroute.premuim and TOPCAT (both payware). Plus I use flightaware, route finder, and Fuel Planner2 on the net. I don't think you can get there from here.
