I have only had the program for less than a month. When I first got it and activated my license all worked great and was fully impressed. Tried using again yesterday and today and every file I import will not create a tool path for gcode. All I get is this error message (see below). Tried the file I first had success with and the same thing, the one in pic. Any help would be greatly appreciated so I can have use of the program I paid for.

You need to select the layer in your operation. The layer name you is selected is not in the drawing file you loaded. It defaults to the previous layer you selected in the last drawing. This drawing must not have that layer.
