I am new to HCD (ver 4.403), but I have a problem programming the controller time on my HC900 C50 controller (4.4 FIRMWARE). The controllers time is not yet programmed. When I click on "set controller time" in utilities tab I get a message: "The time zone data file is missing or corrupted [timezones.dat]" Does anyone know how I can fix this error, or where to start looking? I have searched extensively online, but to no success. My cpu's red light is flashing a code 5, in line with my problem.
