Re-installing on second computer after formatting

[NATHAN]

Hi ,I got my cd for the upgrade and it worked fine on my pc but when i went to upgrade on my laptop it did not like it. I have changed nothing on the laptop and it still says that it has already been registered on 2 comps and to contact mtu. Why is it i keep getting this same problem over and over again?
Also i would like to see a pause button on hoster if possible.

thanks nath.

P.S. i notice the essential disks seem to be labled wrong.
