I presume they have written an extension module, but haven't done their
error handling correctly and are eating some internal information about
the error that occurred. Judging by some quick searches online, the
software is closed source right? In that case, you could try emailing
the provider.

If this is the case, you might try to attach to the extension code in a
debugger, though I'd assume they've compiled it in a way to make that
pretty difficult. Another approach might be not to use the python
bindings, but to use whatever other binding are available (say in C?).
Then you could try to set things up in the same way and see if an error
occurs there and if that error has more information than yours.
