"DLL load failed: the specified module cannot be found."

The demo won't work because importing jsbsimerrors out with "DLL load failed: the specified module cannot be found." The JSBSim DLL isn't on the SF.net page anymore but i found another one. Copied it half a dozen places and it still fails. So I tried to compile the source to make my own pyd but (after numerous code alterations to get the bits to point to the right places) that fails too due to numerous inheritance issues. (E.G: "error C2039: XXX is not a member of YY") I tried just removing the various bits it was complaining about in hopes that it would compile anyway but after 3 files of this I gave up when it started failing on critical seeming bits like "set initial altitude." Can anyone help?
