suddenly I cannot download any of my books at ereader I payed $$$ for and when trying to contact support I am being forwarded to stanza/fictionwise and they even have a link to the ereader bookshelf, but the link does only produce some error message. The support did not anwer yet, they have an awkward webform to submit questions, so who knows if they ever will receive them.

does anyone know what happened?

I've been reading a book, "4 hour workweek" by timothy ferriss. But now all the content has gone. The contents page is there but on selecting a chapter, there's nothing to read. All my other books are intact, it's just this one. How can I get my book back?
