--- Comment #32 from andrew@magneticbooks.com.au 2011-07-26 20:46:31 CDT --- I have finished dumping Windows / Wine versions and compared the results.
The SOAP request in the Wine version is missing ASID and ESID. There is also a question mark around FileHash and MC.
Copying and pasting from the successful Windows request to the unsuccessful Wine request then running through openssl does not seem to work - it reports a 5001 error.
