I saved some views from Composer as EPS files using the Technical Illustration workshop. I do this on a regular basis and haven't changed any settings, yet occasionally when i try to open the EPS files in Adobe Illustrator i get an error "The operation cannot complete because of an unknown error". I have just saved 5 views from one SMG file in Composer as separate EPS files, and 3 opened perfectly and 2 have this error. Is there something i'm doing wrong? Any help?
