Hi, Any suggestions as to why I would be getting these errors? I have successfully transferred *.opf files before, but cannot do it now with either the transfer program or using the "Send to" option from Windows Explorer. Book Port Transfer Error unable to create XML file and Book Port Transfer Error getting Digital Talking Book navigation info. Thanks, Jeffrey -- No virus found in this outgoing message.
