I downloaded Calibre to my home computer. Pulled kindle books from zip file on a CD. When I tryed to send the books to the Nook:

Send to Device
Auto convert the following before uploading to the device.

Yes

Warning: No suitable formats
Could not upload the following books to the device as no suitable formats are found. Convert the book to a format supported by your device.

Okay

Failed: convert book

Now I am very new to this and I am sure I have done something wrong. Just don't know what and where to go.

Please help

Thank you
