Question about Outlook Express

I can open WLM (recently set up in Windows 8.1) once and it works OK, but when I try to re-open it I get the box stating it is "...sending mail using Windows Live Mail" and "Not connected" and nothing else opens....

On occasions I can go into Task Manager and note that WLM has not  shut down so I can end the task and get it to open again.....what is going on? I tried to run Repair in the Programmes but it made no difference...

Any help gratefully received!! If I delete "Windows Essentials" and reload it, do I lose all my contacts, settings, emails etc???

Several times I have had problems with Windows Live Mail 2011 automatically routing mail that I wanted to receive to "junk mail". 

In going through settings I couldn't find how to access and change parameters for selection.

Most of the mail that was routed automatically to junk was common cellphone mail servers such as gmail. 

But today I saw an email with an attached proposal on my cellphone (cellphone is setup for IMAP to leave emails on server). Then when I returned home to my desktop, to download and print the MS Word proposal ; I couldn't find it.

Looking further I found it in "junk mail" on my desktop computer. The email with proposal was from an address that was a companyname.com. I can't think of any reason it was automatically routed to "junk mail".
