Yes, I'm on a Mac. I've been working all night trying to find a solution. Still no luck. The files are in 2013 SketchUp and 2013 Layout.

When I'm in Layout and click on File, Insert, my SketchUp files are greyed out and I cannot click on them. I'm thinking this problem is really something small but I can't seem to figure out why this is happening. I've even sent my file to Layout while in Sketchup and still, cannot load the same file again while in layout due to being greyed out.
