Mac using Windows
 

I have been able to play using bootcamp for about 2 weeks now but i have to have a valid Windows key (which i have) but everytime i enter it i get the product key is invalid. I have tried many other keys that i know are valid with the same issue....

Has anyone running windows on a mac run into this problem? I dont have to many days left and would like to get windows activated, any help would be great!:confused:

Find another key.
