How do I retain cookies with NIS 2012

At the present time NIS is deleting all of my cookies.  I do not want NIS to do this.  I have cookies management software and it works extremely well.

 

Can someone give me a step by step instruction on how I stop NIS from deleting my cookies.  My browser is set properly, so the problem is not there.

 

Thanks for your help on this.
