oSync

Hi all;
I've just installed oSync and am trying to get it to work - I've got the proxy configuration set up correctly and so on, but whenever I try to do a sync it doesn't work (error.log contains one line - "None"). After doing a bit of digging, I found oSync_data in the data folder, which contains the response from the FTP server. The server says:
550 "/duwanis.osy": No such file or directory
Do I need to create that file and manually upload it to the server? Or is there part of the setup process that was supposed to address that for me?

Thanks in advance,
duwanis
