It's a bug with Distributed Folding GUY 2.1 when you configure more than 5000 units for upload frequency.

But the server is always down... I can't run the client ^^
If you are seeing it complain because it doesn't like the -s switch, that sounds like you have the beta client. If you still had the old client you could run with a -if switch and it won't look for the server, you just have to remove that switch later in order to upload.
