The reader is not updated; I live in Hungary, so I can't really send it all over the US.
The new Calibre does not support it, the 6.29 version does not run on my system.
I used an older laptop with XP to install the 6.29, but that does not recognize the reader, either. (Neither does the computer; I can't see it in the explorer as an USB device.)
I did install the Calibre 500 drivers...
So I'm stuck.
