FlexiStarter 7.7 for MAc

I am using a MAc 10.4.11 and trying to run FlexiStarter 7.7.
I am able to setup the serial port (Using Keyspan serial adopter), i am able to setup the driver(Graphtec FC2100-50), but when i create a job, and try to cut/plot, it says its cutting, but nothing happens, then after a while it says job done, but still nothing.
I need help.
