Sounds like you need to install the Graphite Light font on the other machines.
If Archicad can not find a font that has been used then it will substitute another in its place (usually Arial).
If you are using this font in places other than the interior elevation marker (i.e. just plan text on the plan) and that is opening fine on the other machines then sorry I have no idea what is happening.
But if that text is changing as well then I am 99.9% sure you don't have the font installed on the other machine.
