couple of times faced with the Illustrator crash and failure to start. Configuration error "Error 3". While trying to fix, found that somewhere lost file "c:\Program Files\Common Files\Adobe\Adobe PCD\pcd.db" (I am talking about Win XP). Tried to clean a temp folder, but this did not help. Scanned for viruses, all clean, as said antivirus. Reinstalling did not help in the matter too. I know i lose sight of something important and i need an advice.
