When I try and add new products to my markeplace, or try to find out how to do so. I switched to the "Merchant Inbox" the last time I added new things. I tried to upload new items today but it wouldn't let me drag and drop the items in. I logged into Maqrketplace and went to my stores page, then tried logging in and out of SL again but I am still getting the error and it still won't let me drag and drop. I Tried using 3 different viewers including the SL one and it has the same issue each time. It doesn't seem to recognize me as a merchant and won't let me drag and drop anything. I have had a store on Marketplace for over 3 years, possibly 5+ and I am really frustrated and upset by this. 

[I can't sync?]

I added new things to my Magic Box, but when I try and add them to my Marketplace account they don't show up. I have reset the box, synced my marketplace and still nothing. Whats the deal?
