I'm having trouble too. I have taken care of both the Payment Information and Mesh IP Tutorial. Both are highlighted in green but still I cannot upload. When on Aditi I get the message in the upload window that I will not be able to upload on the main grid; yet I can't even upload on there. I even resubmitted and confirmed my payment information. It has been about a month or so since doing the tutorial and when I try to redo it, it shows that I have scored 10 out of 10.
