I hate to just repeat the error, but is DISPLAY set properly?

You can check this by typing echo $DISPLAY.  If you don't see
something like localhost:0.0, then I don't think it is set properly.

It appears as if the software is unable to find your X-server.  Are
you running X locally?  Can you run other X programs from the same
terminal?
