Since yesterday DXspider is not starting. I shows the message "cannot open /spider/data/dupefile" and the process ends.

I confirm that there is no file "/spider/data/dupefile", so according to the documentation the file should be created in the DXDupe.pm module.

BTW, this instance of DXspider is running on Windows.  It was working fine until yesterday.

It is not an issue with folder permissions.  I have already confirmed that.

I don't know what to do next.... I would appreciate your help.  Thanks in advance.
