Homebrew PCBs

The plotter works just fine in every mode I have tried it in, I am 
using WinLINE software to talk to the plotter with success, I have 
also printed directly to it from the Eagle software and get a good 
board layout on paper. It's just when I try to use the scribe 
software links that have been on this board before that it acts this 
way. 

I am trying the scratch software I found at:
