get your pc cillin up, click on i think it is the second last box on your left. in this will be you firewall setting (somewhere... any probs finding it just let me know) and turn it on. make sure that his is the only firewall on. check this by going to control panel in the start menu, clicking security centre and checking the firewall status by clicking on the little arrows. this will tell you if you have a firewall up and how many. if you have your windows firewall on also, take it off by clicking internet options or the other thing there and turn windows firewall off. this clear enuff?
