'PostScript document text conforming at level 3.0 - type EPS' files are generated from another application. When I try to import them I got "Invalid file format". That's why I converted the files to a format I was able to import. Actually that's one of my questions: Why I'm able to import eps level 2 but unable to import eps level 3 into Mathematica?
