I had bought a Lenovo Yoga 2 Pro a couple of months ago and the screen had cracked when I had opened it on the day I received it. I had installed Microsoft Office Home and Student Edition on to it before it had cracked, however. I received a replacement with the same Office loaded on to it. However, when I open up any Office application (Word, Powerpoint etc), it says that Office is unlicensed and I am unable to use it. What must I now do? Must I purchase Office again? Must I give MS double the amount of money for Office because they couldn't be bothered to address issues like these? Should I consult the retailer I had bought it from????? I don't know what to do now.
