Lot not uploading to exchange

RachelShennan

I have been trying to upload a house to the exchange. It lets me 'share' it, so I get it onto the game launcher panel, then I click the upload button and it tells me it's successfully been uploaded. I then check 'my studio' and it's not there, then I go back to my game launcher and to the house and the picture goes faded and wont let me re-upload?

HELP???
