500 unrecognized command.

Attached is the log of my server. I Have never had any problems previous to today. The only thing that happened is I downloaded the update. I can connect as you can see. BUt when I drag my file to the client, nothing happens, my file disappears out of the queue and nothing happens...Any suggestions?

Thanks in advance,

Christina
