Layers not found

Im having a problem all of a sudden. when i import a dxf into the program that has layers and sheetcam recognizes the layers, but as soon as i go to an operation it gives me an error that lhe layers are not found?

In your operations you need to select the appropriate layer in the ‘layer’ box.

the layers are checked off. the moment a open an operation and click on the layer at the bottom it says layer does not exist. I ran this program a few days ago no problem.

Open your cut operation. The ‘layer’ box will be empty. Select one of the layers in your drawing.

I have done that!

Could you send me the job file (file->save job) with your drawing and the operations set up.
