How do I cleanse my computer from Party Recognition?

[MAxx]

So, I want to open a new party account after closing all prior accounts. I erase the program and erase internet cookies.
I reinstall party and try and signup as a new account. However Party recognizes me and states that for purposes of collusion prevention, they will not allow multiple accounts for the same user.

Can I do somethin like run regit and delete their implant. How do I get them not to recognize me?
