What does mean this error ?
Error talking to classification server: "Error 32 fault: SOAP-ENV:VersionMismatch [no subcode] "SOAP version mismatch or invalid SOAP message" Detail: [no detail]"
This is probably an error related to the update procedure or a bug in the code. Since it's an open source application, there might be errors. However, I recommend downloading the latest version from the official website. I have used it and it doesn't display this error. I am using Windows 8.1 X64 Pro.
