unable to open EPS

Hello,
I am having trouble with opening ESP files in Adobe Illustrator 10 / Freehand 10. Freehand shows “X” mark and Illustrator says it is created in a newer version but it is not.
Appreciate your input in advance.

The file could have been corrupted. If it was emailed to you ask the sender to zip it first and then email it. Otherwise try to open it in other programs like Photoshop or Preview.

I’ve got this before, and when I have, the file did turn out to be generated in Illustrator CS (the latest version)…
