Firewall On Bitdefender Internet Security 2008

Hi folks! I downloaded the trial for the BitDefender Internet Security 2008 and everything works just fine eccept the firewall won't save the Programs i Add to the Traffic settings such as Internet Explorer, Yahoo Browser and some Programs i don't want to connect to the internet with.. Here is the thing, My Internet Provider is Yahoo AT&T Fast Internet Connection and everytime i Boot my System (WinXP), The firewalls Pomps asking if i want to allow Those Programs which i just Mentioned And save everytime i hit allow... I Called Tech Support and they told me that i Need a Static IP?? So i Called AT&T and asked them how i Can make my Connection Static because BiTDefender Firewall Recognizes My Network as a new network everytime my IP is Changed by AT&T(Which Happens everytime i boot my Computer)... AT&T told me i Need to buy a Router To make my IP a Static IP. So my question is; Do i have to allow/deny my programs everyday of my life if i don't buy the router? or how does the firewall work for people that have Dial Up Connection??

I'm already a BitDefender Antivirus 2008 Customer and i really want to get the Total Security suite but i'm thinking twice because of the firewall settings, i just wanna B able to save my programs in the firewall settings but it keeps asking me everytime i boot, for some reason is not saving and the only solution BitDefender Support over the phone told me is to get a Static IP Adress so i won't be Pomptd again
