I am having problems plotting to a .plt file. I have installed by Repro companies plotter onto my machine, and followed their step-by-step, but for some reason when I attempt to create a .plt file, an alert window is displayed that states, "Cannot open file... Abort, Retry, Ignore". All three of these options have been tried and tested with the only result of a 1k plot file when ignore is selected. I am told that my .plt file should be the same size as the .dwg file itself. What gives?!?!
