One of my texture files had a name that was 113 characters long. The file uploaded OK now so it's good. I didn't know that thing abou tthe 100 characters so that's something to look out for in the future. Thanks!
I am trying to upload a file to the hub and I keep getting this message. I've tried five times now and always get this. I've never had this before and I've uploaded probably a hundred files over the years.
