need to re-install but can't again

[NATHAN]

Hi ,i need to re-install but i can't again, i wrote down all the updates for my pc last time but have formatted again and re-installed all updates and hoster still wont install. I was wondering if you were to be very very kind and re-set my details for one copy and tell me if this next thing would solve my problems. If i were to install hoster on my external drive would it work when i pluged it in again?

thanks nath.

p.s. still can't order hoster 3.0
