in one of my games i disable it and now i cannot able it again.... i even reinstalled the game but there isnt coming back. Any suggestion for making the pop come back?
Assuming you were refering to the alerts at the top, like "Open Council Position" and such and deactivated one, then
look at the right of your window. There is a box with information (armies, demesne, etc), called the outliner,
that has a configuration button.
To quote the Wiki:

In order to restore disabled or dismissed alerts:
- Open the outliner category configuration
- Check the box Disabled alerts
- In the outliner, click on the alerts that need to be restored
After you clicked the disabled alert it will pop up again at the top, if the reason for the alert is still true.
