I guess I've made the mistake of upgrading? I've been using this program for sometime but haven't tried using it since switching to Adobe CC2014 and also now running Yosemite - no matter how I save my Illustrator file I get the error message that "There were no usable vector paths in this file" Any ideas???
Be sure to turn off the "Use Compression" setting when saving the Illustrator file. If you are still having problems, try saving the file as an older version of Illustrator such as version 10 or version 8 and see if you are still having problems. If you're still running into issues, please send the Illustrator file to me at firstname.lastname@example.org and I'll take a look at what you're running into.
