dp_sidelight_panels.gsm Error (System Error -1)

[Anonymous]

Hey guys and girls,

something very strange is happening with a particular archicad (12) object - "dp_sidelight_panels.gsm".

certain computers in the office are recieving the error (shown below).

The strange part is, the error in the object only occurs in certain files (Note: they are all reading the exact same library). Is it a problem in the archiCAD file or some computer problem?
