Unknown error reported by xfServerPlus

The server returned an error that was not recognized by the client. Check the xfpl.log file, which records the error even though the client is unable to receive it. This error usually happens when an older xfNetLink Synergy client is communicating with a newer xfServerPlus server. To solve this problem, update your client version. If your versions already match, call Synergy/DE Developer Support.
