Exception processing message error cannot open illustrator

Question

I have Illustrator CS4 running on a PC with double quad processor and 4 Gb or RAM, running on a XP-Professional platform.
I have had a lot of problems with all sort of crashes, which have delayed my due date for these projects and no answers on any of the reports I have sent.
Anyways, today I came and turn on my computer and when trying to launch illustrator this error appears.
'Exception Processing Message c0000013 Parameters 7c7df5f8 9cc8b118 7c7df5f8 7c7df5f8
It comes with 3 options Cancel Try Again and Continue
If I select Try Again it continues poping up at forever basis.
If I select Cancel just kills the opening of the program
If I select Continue, the message repeats itself several times until the program opens, but then once I'm working on the file, another message appears saying, FILE NOT READABLE.
I have more than 200 Gb free on disk and I have not moved any file from it's original location.
I am just one step of getting fired if I cannot complete this task by the end of today and the program is killing me, please help how can I fix this problem?
It is incredible that I have these many problems for one program.
Thanks.

Answer 1

It is running in a 64bit OS, not 32, and amazingly all the programs work just fine exce
pt illustrator, not even photoshop, autocad, inventor, solidworks....
Intel(R) Core(TM)2 Quad CPU
Q8300 @ 2.50 GHz
3.99 GB of RAM
The CPU Usage  is about 24% Max.... when doing tasks
And the PF Usage is no more than 1.13 GB RAM Which should be more than enough to handle the program don't you think?
I wonder how the people using the minimum requirements work with way less problems than these?
Yes, it should be a dll problem, I wonder how can I fix it.
