bypass Guest Pass

my mate just gave me a copy of the guest past anyway to bypass the limit of 7 hours and 14days?...
ive heard its possible but forums dont post how to do it :/.
any help will be nice maybe a vm or pm, do i need a crack or something else :/

Change IP...?

Once the code is used, it's used. It will cease to be valid.

As for increasing the time, I have no idea.

All I know is that it was well worth my $60.
