Perhaps you are using an earlier version, also the plugin will only work using the parallel port.
I have written some basic instructions which are here; http://www.cooperman.talktalk.net/Engraving.pdf
and the latest version of the DLL can be found here; http://www.cooperman.talktalk.net/Engraving.dll
There is some more info on the plugin in this thread; http://www.machsupport.com/forum/ind...html#msg131346
