Turning ooff timer.

[Age]

How do you turn off the timer as I playing Egypt and I only have 20 turns left early era?I have set everything before the campaign to 2000.It still comes up with you only have 20 turns left.There must a be timer some where else as I am practically 50% covering the map.I just need more time to claim victory but I know I need more than 20 turns.

Than there is this that keep poping up in my Viking era and I have that set at a later date as well.when this pops up game crashes.
