Whoop…okay…
I think the loading problem with that one is the map components are all vector. That’s going to result in vector fills overlaying other vector fills…and for vector fills, you just get one color out of the deal with Graphic Engrave. So if it could load (it generally doesn’t when you have overlaying vector fills…you’ll get the “We’re sorry…an Unexpected Error Occurred” message) the results would wind up just looking like a solid block of color. (It’s got over 142 thousand nodes in it too, so loading would take forever.)
Best thing to do with that one is rasterize the map components. The photo-engrave setting is going to give you the option of different “shades of gray” visually by spacing the dots a little, and it might be able to render it. (That’s still a lot of data, so expect it to take a long time to process.)
In addition - the cut lines are actually extremely thin filled closed shapes, not vector paths with a Stroke color assigned. They will try to engrave, not cut. That’s usually the result of doing an Auto-Trace on paths that you imported from some other program, or on a raster image.
For that, you need to go in, release the compound paths, and delete one of the lines…it’s going to be hard to do because they are very close together.
(In the future, when you use the Live Trace in Illustrator on something like a Map or a line drawing, you will want to do a Centerline Trace to avoid double cut lines being placed around your drawn lines. Tutorials: Avoiding Double Cut Lines In Your Designs and Centerline Trace in Illustrator.)
But taking care of those two issues should allow it to load. I’m going to try to clean that one up a little and see if I can get it to load, but you might prefer to do your own cleanup, so you can get started on it while I mess with it a little.
