Playspan Error. Need IP Changer for Vista.

Because of the error i got from playspan i now need to change my ip address.

Can anyone suggest a good Ip changer that works well with vista and works easily? It will be greatly appreciated.

And i need someone to answer these questions:

1. Will i be able to change back to my original ip address after changing to another one?

2. Will anything happen once i change it? any downsides?

Thanks.

idk .. google it .. i had an ipchanger but it didnt worked.. (on playspan)

what do you actually do on Playspan to earn the points? offers?

today i think that there arent any free offer to earn points..

i go to free and says that arent free offers ..
