Adobe Illustrator error “not enough memory to open the illustration

Hello tech experts,
I did not have any problem or issue while installing Abode Illustrator. Now I am facing errors day by day. Today when I open the existing file or when I try to create a new one I ended up with an error message. The error message states that there is not enough memory to open the illustration. How I can solve this error? Please help me. Thanks in advance.
