I recently updated to Adobe CC and my computer can no longer handle the same workflow I have always had. CC is eating up my memory!! I can't even have the web browser open with an AI file. Suddenly in the middle of working on the most simple project I will get a prompt that says Illustrator cannot finish previewing there is not enough memory. And then all of my artwork goes into outline mode. I since have doubled my memory in my computer to 8GB and it has only gotten worse, now I cannot even OPEN a file! This is a terrible terrible issue and has made my computer unusable. I am thus far not a happy customer... can someone help!?
Please share the version of Creative Cloud application that you are using, so that we can try to assist you appropriately. We would also request you to check which process is using memory while you are working on a project.
