Problem: The latest generation of web servers from Microsoft (IIS 6) refuse to serve any file unless it has a "known extension" (i.e., .bin, .doc, .exe, .jpg, .pdf, etc.). Unfortunately, NoteWorthy Composer (.nwc) files are not yet in the "known" category.
Solution: I have modified each file name by adding a second extension of ".bin" (indicating a binary file) after the first extension of ".nwc". This permits you to Save (download) the file, although you cannot Open it (view its contents) on-line. After you finish your download, manually rename your copy of the file by removing the second (.bin) filename extension. Then (assuming you have NoteWorthy Composer software installed on your computer) you should be able to open the file just by double-clicking on it.
Good luck!
