It seems that some people had problems updating the book.
I guess it was my mistake to assume that everyone is familiar with the DOS command line (I consider Windows to be just garbage put around DOS
)
I also made a mistake on my web site where I have the syntax for book update as 'naum /UB {pgn_file}'. It should be just 'naum /UB'
My appologies to all who had problems. For the next version, I will make this process automatic or optional.
