layer issues with Mastercam

Hi, I have downloaded the newest version of Sheetcam
And i loaded a dxf file created by MASTERCAM
The issue i am getting is it has"UN NAMED LAYER, LEVEL 1

And the issue i seem to be getting is that the tool path is not generated so as to be viewed
Otherwise it seems to work ok

Anyone have an IDEA??

Bill

here is the dxf file if someone wishes to give it a try
