I am really frustrated here. I am having a problem with my Adobe illustrator cs2. The problem is, that every time the program renders something or finishes (let's say, rounded corners) the loading bar is complete but does not leave the screen, and clicking "stop" does not do anything. This causes the program to get stuck. I think this is a problem with the RAM because when I try to change something or get a preview of a change I get an error saying:

"The operation cannot complete because there isn't enough memory (RAM) available"
I have tried restarting and changing the AI preferances file, but nothing seems to fix the problem. If anyone knows how to fix this problem I would very much appreciate if you told me!
