Hi, so i just went and brought a new computer and formatted my old one which i previously installed Microsoft office 2010 on with no problems (its a 3 key Licence) I have a copy on my laptop and i had to re-installed it once on my old computer because it failed to boot but i thought because its on the same hard drive on the same install it would use my 3rd install chance but when i try to install my copy on this new computer it says the key i have is invalid and that means its only allowed to be used on my laptop I'm a little annoyed because i need this for my studies, but i guess it will most likely end up with me calling my countries Microsoft Number and explaining my situation to them.

but any help on how to fix it would be appreciated thanks,
