The program crashes after this error message.

Need help for this one,
I am working on a project and I am trying to set two range, the first range i set is doing fine but when i tried to set the second range it says not enough memory to create list. The program fails to respond and what i have to do is open the task manager and close the application from there.

After Effects: not enough memory to create list.
