After a system hardware fail, I lost my mainboard, I have to replace with new mainboard and reinstall whole system.
And I need activate now, thanks.
I'll let Andy and Alex now. It takes typically 12-24 hours depending on the time of day/night it is in Australia.
I've reissued your activation so that you can be sure it'll activate!
(Just want to quickly mention that activations should only be used on one computer)
