Problems with direct export in Vista 64

1) The options to set the association appear to work for firefox but generate an error for IE8 "Failed to set data for '' " is the message.
2) However, nothing works. In Firefox, if I set the association between application/x-endnote-refer and the correct version of biblioscape, it goes through the motions of firing up biblioscape but nothing is loaded.

Any suggestions?

What is the data source URL?

What is the data source URL? I want to give it a test.
