Unknown error occurs when trying to open ANY .ai file

Question

All of a sudden this morning,I cannot open ANY .ai file - I get the message "An unknown error has occurred". I can open .eps files without problems.

I have tried opening files on both my local hard drive and on our server - same result.

I did update Illustrator this morning after receiving notification about the update, but the problem occurred BEFORE i did the update - I decided to try updating to see if it would fix the issue, but no luck.

I have tried quitting Illustrator and restarting the computer, but no luck.

Please help - I am dead in the water if I can't open my files.

Please contact support.Contact Customer Care You need to be logged in and at the bottom of the page there is a chat option (unless you have a team license)Monika,Just wanted you to know that Customer Care fixed the problem - once we trashed the Preferences folder, the problem went away. I was kind of thinking it might end up being that because in my previous experiences with InDesign when I have encountered odd problems, trashing the Prefs has fixed those problems. Luckily, my use of Illustrator is fairly basic and I don't have any elaborate settings in my preferences.

One more thing - I just tried opening some of the .ai files in Photoshop and they open without problems. Of course, this does me no good because I loose the vector graphic format if I try and save them. But it does show the issue is with Illustrator and not the files.
