HI Delphine, So the reason you couldn’t upload is because you uploaded your September challenge a bit late (October 1st), and our system only allows members to upload 1 video per month. The best solution would be to email us a link to your OCTOBER challenge video, and we will review it from there. That way you should be good to go and upload your November challenge this month as well as the months to come through your profile again, as long as you post it before the last night of November (los angeles time). Thanks! info@silkstars.com
