Download issues

Each time I click to Download the video it reads "We're working on your video and you will be able to download soon" but the download is not working. I have paid for premium access. As I thought it was due to a lack of storage from trying the free trial however upgrading to premium access is not sorting this issue. I have now had to re-do 3x edits of my video in an attempt to save this!! Need help urgently.
