Me too, I thought it may just be my account since no one else is complaining. I’ll alert the web maintainer that there looks to be a problem. It took me 4 attempts (various errors on the first three) to log in just now.
If you will upload a dxf file (as noted you likely will need to add a .fzp extension to upload it) I’ll try it in Eagle2Fritzing, otherwise one of the solutions that @opera_night suggested above may work but Eagle2Fritzing is all I’m equipped to try.
