After downloading eBooks purchased on lexcycle.com to my desktop, I followed the FAQ instructions to export it to Kindle using the Stanza desktop app. I saved it to the Kindle connected to USB, in the "documents" folder.

I appears in the Kindle, but when I try to open it I get "The selected item could not be opened. Please use your computer to visit Amazon.com and clin on "ManageYourKindle" on the "Your Account" page for help in solving this problem.

Of course the amazon page has no help on this issue.

When I open a pdf file in Stanza, my "Export as" from the file menu is greyed out and hence I cannot use it. I enabled sharing and anonymous sharing and also plugged in my kindle. Looked through the FAQ and did not find anything that fits. Also browsed through the forum and couldn't find anything there either. Please help.
Thanks,
