Travel with ARCdroid/illustrator? Can you help me?

I’ve had our droid now for about two years and I absolutely love it but recently, I’m experiencing some problems with my illustrator files being imported. Most of my files are very small, so I know it’s not a size issue. I typically design in illustrator and export to DXF. Lately I’ve been getting an error message saying “no valid shapes found”. Often they are just shapes which I’ve included in the photos. Sometimes it’s a font and I just create an outline for. I’m stumped. Again, I’ve been using this machine for about two years. I have soft booted and restarted. Any suggestions out that would be great. If you’re creating in illustrator can you give me your five step process to exporting your file?
