Go to your file silenthunteriii\data\menu\en_menu.txt and check that:

b) it contains the messages that you think are missing.

Check also the NYGM3.6B mod that you have, and compare the file dates for its en_menu.txt with the one described above. Probably the two copies of en_menu.txt differ, which implies a faulty installation.

Otherwise, check H.sie's documentation for the additions that he says you need for his V16B1 mod, and cut and paste them at the bottom of your existing en_menu.txt file.

Don't forget to make back-ups of files before you change them.

Good luck!
