Illustrator cs6 crashes at launch

I've been also experiencing similar problems with illustrator crashing. I'm on a maxos 10.7.5. A work around I read elsewhere seems to get me going but is a probelm in itself. So i read to clear the apps preference data (holing shift+option+command during program launch) and everything works fine. My initial probelm was the inability to save .eps or .png file formats but I then started getting other crashes. From not being able to open a document, not being able to place .eps files, to crashing when creating a new doc and now when launching. Hopefully this will help in the interum till some kind of patch fixes this.
