Hi folks,

I'm having the same issue. Illustrator CS3 files WITH TEXT in are bringing up the "An Unknown Error Has Occurred" error message.

I'm using Windows Vista with Illustrator 13.0.2

I was using 13.0.1 which gave me the same problem. Updating to 13.0.2 made no difference.
I've reinstalled CS3.
I had Avira AntiVir installed but uninstalled it.
I don't have a Zune.
I've deleted my Settings folder and that hasn't helped.

Files with just images and shapes work fine, it's just text that seems to trigger the error.

Please can someone let me know what to do as I've just lost a morning's work trying to fix this, and I'm not a happy person...
