Can't convert flipgrid file to vboard file

  • I have a large (<100 MB) flipgrid file that needs to be converted to a vboard file. I have tried the drag and drop method into myViewBoard whiteboard but I always get a message saying that the file can't be imported. I went to the website and to the file conversion request feature. I successfully imported the flipgrid file but it has been at "progess" for several days. I need the file for school soon. Can you please help me?
