Lordy i know how it is, my laptop used to be a mess after first getting it though I've managed to get it working properly. Hopefully you figure out what the problem is, and dont forget to save! 8")
Ugh!! I hate that!! I had this issue with mine and found out that it was a Microsoft update issue. For me, I had to go in and manually download it and it hasn't done it to me since - there is a rare occasion once in a blue moon but it's ok. Either way, I know the pain!! It's why I have my photoshop on auto save now.
