Considering they owe back from 6 months ago, I would hope that has nothing to do with it.  Would be an awfully shady way to try and get out from paying any.  I don't have many left, I stopped using their system to order when they stopped paying the rewards out.  Regardless, to shut it off is absurd.  I can see not allowing new proposals to be built, but to shut it off after just several days of notifying me is just bad business.


Edit:  They owe 9 months back now of rewards dollars.
