Windows Live is acting strange, not showing on computer, only a portion of the program can be seen and no emails available to view!

I have two hotmail accounts, which I open in Windows Live. This program has been working for very long time without any problems for me. However, Windows Live started acting odd a few months ago and I could not open my one of my accounts, and the emails from this account was showing up in my other email's in-box!  I've tried several fixes I found online, but nothing seem to work. Recently, I started getting emails sent to each account of the smae exact message to the in-boxes.  Now I can't open Window Live or seen any of my emails.  I have several special folders that contain pictures or documents I saved in these Hotmail accounts.  Have I lost all my email folders/info, and how can I get my Hotmail accounts to open again in Windows Live?  Also, when this started.. some of my contacts either disappeared, or return to their original form/info I was given or used for each email buddy.. Its like I never had any of them.  Anyone have suggestion or idea why this is happen and how I can correct the problem?
