I need some help...

[AiboPals]

I haven't done anything, what I do know is my father using another computer without the proxo, using the router which has a static IP has no trouble whatso ever, and before I used proxo that was the IP showing for my puter too, so what I need to know is how to change it, the site banning me is Neopets I have been accused of cheating and now every account I make gets *frozen* even though I have never cheated
