I start Illustrator CS4 and it doesn't want to open past updating font menu. I can get the program to work when I delete the AI preferences, and the font caches, and restarting, but it only is a temporary fix because it will happen again even in the same day. Any suggestions, I haven't installed any new fonts or anything.
It often freezes up too and won't let me use my task manager. I use windows xp.
