Steam DLC cannot be enabled now.

[RawPower 0]

Trying for days to find a workaround to install & ENABLE the DLC for Flight.  GFWLive Marketplace fails to show purchases with keys there now. I can login in to Profile in game but it is OFFLINE and then takes 5 minutes to ask for 25 character game key which Steam never provided...only DLC keys none of which work to pass. (Test Drive Ferrari has a key and was accepted to go online in that GFWL steam game so servers work.) So I have no Flight DLC in long numbered folders in Users Xlive folder. I am thinking that if someone had a functioning DLC with all the Xlive enabled content and posted it to One Drive or Dropbox for public download I could copy it to mine and repair the game. I downloaded all the DLC from web as Steam will not even DL them if checked. Put it in game folder with new cfg file but it does not install it into Users DLC. Only Core Content shows in Flight Toolkit Addon Manager and that program does not DL anything. Only installs .flightAddon files you have to find somewhere never provided. 

So please post your enabled Xlive DLC folder in a OneDrive location. I think it could work if I use FTKit nonGFWL mode.
