Hi I had issues with my acer aspire timeline laptop and had to replace motherboard however now windows won't activate stating message "the windows 7 premium product key you typed is invalid for activation". I formated drive and reinstalled and product key is the original and correct...what do i do, i needed new motherboard as i can't afford a new laptop and all else is working but i need to authenticate windows.  HELP!
