Hi,
Some hardware changes, as well as reinstalling Vista, will necessitate a
need to reactivate your installation. As your Product Key has already been
used, the "over the 'net" activation will report the key as being in use.
The solution is to use the phone activation method. If the automated
sequence doesn't work, just hold the line for a real person to activate it.
