Hey Hal – would it be possible to upload one or two of these files to Dropbox or similar and PM us a link?
If you don’t have anywhere to upload them to, just ping @support and someone will be able to help you upload them directly to us.
Has the spinner gone away in the top-right? If so, your content may still be getting identified.
In any event, screenshots would help here. There are some uploading instructions at the end of this post.
