My Surface Pro came with Office 2013 preinstalled. When I upgraded to 8.1 it deleted my copy of Office. There is no keys or discs or anything like that included in the Surface Pro packaging and my warranty already expired, which is weird since I got it in February and it expired in August. 6 months warranty? Anyways, without warranty I can't contact them by chat or phone to ask. Anyone else have this problem or, better yet, a solution?
