Updated:
server2.zip
I added a protocol parameter in LibraryServer.config which allows you to configure the content server to use either either ereader:// (works with eReader 2.x) or http:// (works with Stanza and old versions of eReader).
Tested on eReader 2.1.1 and Stanza 2.
Mizumo -- if you describe the difficulty you're having I can try to help diagnose.
