My messages disappeared on messenger.  I didn't change to not save them.  How do I get them back?

nothing appears about the list to - edit - delete - or add
I've tried the same way as answered in previous questions as well as right clicked for a "delete" option, but I have nothing...

my inbox says (1) but nothing in there...then it flickers to 2 or 3 but only 1 message gets through....always (1) message in inbox...but there is none!!!
See the caption above. nothing more need be said. I did not authorize this deletion!

How do I find my contacts?   Now PEOPLE comes up with nothing below it.  PEOPLE is something new to me.

 

Also how can I remove one person/email from a group that I send to?

I can edit and delete people in my contact list but then I go back to hotmail and nothing changes there.  It's still all the old information.  Why is that and how can I actually change my contact's information?
With the new format-I cannot figure out where to go or how to put a new contact on my favorite list. I see nothing to click like on the old format!
I had asked this question already and was told in the Reply that I should click on 'Options' in the tool bar etc.etc,etc.   There is no 'Options' in my toolbar.  There are only two words there and nothing that led to adding names to my Groups folder.  Help!!!
