Hey is anyone else having issues uploading? I have an effect that I have been trying to upload all day. I've tried multiple computers and browsers. Both my promo and explanation video say "Media successfully attached" yet when I click submit I get a pop up saying "Please upload both a preview video and instructional file." I've tried probably 15 times. Any suggestions? Does anyone else have this problem? If it's any help the video I'm uploading is HD and nearly 20 mins long (764mb)
