I don't think Fictionwise reads this board...
From the Fictionwise TOS:
9. Ebooks. After purchasing any downloadable eBook or product from Fictionwise.com, it is the Fictionwise Member's responsibility to download the eBook or product within 1 hour of purchase. If you believe an error has been made in the purchase, please do not download the eBook (you must contact us explaining the error at firstname.lastname@example.org). Once you download the eBook, then it is impossible for us to refund you for it. Please note: Because of the constantly evolving nature of the eBook industry and eBook formats, we do not guarantee that eBooks you purchase from Fictionwise will always be available in the formats that we "currently" support. That is why it is important that you download the eBook in the format of your choice immediately after purchasing.
Fictionwise, however, will make efforts to keep the product listed and available for download in the Fictionwise member's "Bookshelf" for one week, and longer when possible -- but this is not guaranteed.
Even more significant, the following is at the bottom of every emailed receipt:
NOTICE: You should download your purchases as soon as possible. Fictionwise will maintain your purchases on your bookshelf for at least a week, and longer if we can, but that is not guaranteed. Make sure you back up your files.
The good news is you will probably have access to your books when things straighten out with Fictionwise distributors. This is why I have several backups of all my books, including an online storage site.
