I have several items on Marketplace, but only five are active. I am unable to activate any other direct delivery listings. When I try to do so I receive one of two messages... Successfully Updated, or I'm taken to a new window that says Sorry for Your wait we have been informed of this problem and will look into it shortly. Thing is, I've waited and continuously tried to activate my listings for nearly three weeks now. How do I get my direct delivery listings to actually activate?
