Illustrator 'quits unexpectedly' every time.

Question

Hi all. I bought the Design Premium Student Edition CS4 for mac os a few months back and had trouble just getting it installed. At first it was the serial not being accepted, no matter how many the Adobe help desk gave me. It turned out that I had to make a completely new administrator account. Still don't know why.
Everything was fine 'til a few weeks later, Illustrator would close halfway through working on an assignment, and still now it wont open at all. It brings up the loading page then closes and brings up a box with "The application Adobe Illustrator CS4 quit unexpectedly." and so on.
I have uninstalled, reinstalled just illustrator and also the whole of cs4. I have tried deleting all the preference folders. I've moved all the illustrator folders onto the desktop and tried opening from there, still nothing.
I have called Adobe support people but I am sick of getting no results. I am hoping that someone else has had this problem and had it resolved.
If there's any other details I missed that you need to know to possibly help me out, let me know.
Any help would be appreciated. =]

Benvegnu,
When the folder moving and the CleanScript do not help, you may try one of the following (with tests):
1. Corrupt font(s): you may move all fonts out of the  Windows fonts folder (and move them back in);
2. Firewall interference  (especially if more than one is running (XP SP2 adds one if activated)): you may  turn them off (and on again);
3. Some versions of Acrobat generate many  temp files. Too many (64K) causes the problem: you may search and destroy Temp  files;
4. Some other inconsistency caused by Adobe Acrobat/Reader: you  may try uninstalling and reinstalling (a newer version).
5.  Incompatible/old printer definition file for the default printer: you may  upgrade the driver, change the default, or set the PostScript driver/PDF to  default;
6. Using a US/English version of Illustrator with Windows set  to a different language: you may enter Control Panel>Regional and Language  Setteings and change to English (and change back).
7. Quicktime/iTunes: uninstall Quicktime and make sure the Quicktime folder is deleted in the Program  Files folder; and/or uninstall iTunes.
If none of these possible solutions work, have you made any (other) changes to the PC between succes and  failure? New software loaded?
Otherwise, you may have to try Customer Service again.
