dxf layer import problem

Hi, For 10 years I have been importing .dxf files from Alibre to Sheetcam, and everything has worked fine. I now have a laptop and I am struggling to get the separate layers to import. When I look at the layer dialogue, I just have ‘Colour 7’ as the layer and none of the correct layers available. When I export to a dxf it gives me the option of choosing a dxf version, from 14 up. Any help would be great, as I can only now use the PC for doing SCam whereas my work is all now on the laptop.

When you import, there is an option to use colors as layers. You must have checked it accidentally.
