Since you want to keep spamming this everywhere, I'll speak up and tell you what you won't like to hear: you aren't RL's target customer, and expecting them to fix the issues you're having is both unrealistic and impossible.
iClone is positioned first and foremost as the "one-stop solution" for creating animation -- it's why they now have focused their efforts on incorporating things like PopcornFX and fixing DOF. They aren't really trying to be a "create animation here and use it elsewhere" product, even if they hint (through 3DXChange) that it would be possible. Hell, they haven't even updated 3DXChange to a 64 bit program or changed its interface in years. That ought to tell you that your situation is EXTREMELY low on their priority. They may not EVER update 3DXChange, but if they do it may well take another few years, as will any help for your own situation.
If it's possible to do what you want with the present iClone I suspect you'd already have been helped, although that doesn't mean you can't continue to ask for RL's assistance through a trouble ticket. But the real bottom line is it just may not be possible, and for sure they won't be fixing it if that's the case, at least not in your project's lifetime (which apparently is this week, given you need it yesterday). If I were you I'd move on, find another way of doing your project, work with iClone's limitations, or do what you want in Unity with the iClone assets. That's probably as good as it's going to get.
And don't shoot the messenger -- sometimes someone has to give you a reality check, and I'm just trying to help, as harsh as it might seem.
