I own New Orleans Pianist, Blues and Latin, all of which choke on my WinXP laptop with the error message, "PG Music Font (PGMUS.TTF) is not installed. Make sure PGMUS.TTF is in your Windows or (Win95) System directory. at: 004B6C88" when opening the notation window. And when you close the window I get an "Access Violation" writing to addrexx 0x24... The fonts are in the correct location and I've tried the 64bit font update for BIAB. Does anyone have any other ideas/suggestions? All three applications worked properly on an older (now-dead) winxp based system.
