Improperly treated as an ASCII file
This is caused by improperly downloading an NWC file as an ASCII file, usually from the Internet. This can be the fault of a web server that has not properly set the MIME type for NWC files to a binary type. It can also be caused by someone downloading an NWC file using an FTP program using an ASCII protocol. This is not the fault of NoteWorthy Composer, and there is nothing we can do if the Recovery effort fails.
