I know with steam if you get a ban thats it your account is banned and all games linked to it unsure how it works stand alone
The op doesn't deserve help because of the above bolded.
You need to change your Ethernet Adaptor's MAC Address, once you have done this, you will loose interent. You then need to restart your modem.
If you don't loose internet, then your MAC hasnt changed and you need to try changing it again.
To see if its changed, type ipconfig/all into command prompt and should see the "Physical Address" has changed.
only just noticedits a modem/router in one,now when i log into my router online with virgin is there any way to change my ip address there?
