Hopefully you find the solution to your issue in the video iam717 shared. Else, I can offer to take a look at the files. With large files, you can share a link to drive/dropbox/... directory you uploaded them to.
they are hosted on svgshare.com, the site has some downtime ocassionally. i can put them somewhere else if thats better (now i linked to the demo files in the github repository)
