heyas!
i just downloaded build 4.0.13 i think is where the .'s go. anyway, um... there's no text anywhere in the interface, either in the gl or dx versions (non cuda). no letters, no numbers... buttons, tooltips... all blank.
i have an older system; could be me? did you change fonts or something? below are some specs from a spec-grabbing thing that may or may not pertain to 3d coat.
