font problem - drawing not loading - OSX

hi,

I've recently moved over to Draftsight from AutoCAD, and very impressed so far.

I have a issue with some of my old drawings which use the  'century gothic' font. These drawings will not load unless i remove the century gothic font from my mac (disabling the font does not help)

Is there a file somewhere which is corrupted or anything else that would fix this problem, so i dont need to uninstall the font every time i want to load an old drawing.

Thanks
