New Key URL

The old one (from your 404'd blog)
http://[SDXdomain]/WebStore/Account/SDMAuthorize.aspx?oiopu=[oiopu]&f=[fileID]&oiop=[oiop]&dl=[dlSelect] (not .ashx)

Results in

The current download configuration has changed. You need to remove this client from your machine and download again from the webstore; you can find your download from the Your Account section of the site once you have signed into the system.

As that new client crashes for me, I was trying this project.
Anyone able to get a new URL?

You can try sniffing the request using developer tools in you browser. When I did the reverse engineering of original SDM, opening link from SDX file in ordinary browser, not SDM and clicking Download generated the request, but in UI nothing happened. Then, in returned XML there was everything necessary to download and decrypt file locally.

Doesn't seem to trigger an Ajax any more, sadly.
Also can't sniff the client, as it keeps crashing :/

Try /WebStore/Account/SdmAuthorizeSDCN.ashx that the request would be
