Question about Outlook Express

Windows Live Mail keeps prompting me for my password on one of my three email addresses, (two work OK) I changed my password but still I cant send or receive e mail because it doesn't recognize the correct password. The pop up box keeps coming up over and over asking me for my password even though I keep entering the correct password each time.  EMAILS OK ON MY PHONE OR TABLET NOT USING WLM

Unable to send or receive messages for the dsl.pipex (jwinfo) account. An incorrect password was entered. The next time you send or receive messages, you'll be asked to enter your user name and password for this account.

Server Error: 0x800CCC90
Server Response: -ERR Authentication failed.
Server: 'pop.dsl.pipex.com'
Windows Live Mail Error ID: 0x800CCC92
Protocol: POP3
Port: 110
Secure(SSL): No

An unknown error has occurred.

Server: 'SMTP.choiceone.net'
Windows Live Mail Error ID: 0x8007007A
Protocol: SMTP
Port: 465
Secure(SSL): No

What is the answer to remedy this?

I recorded a video approximately forty-two minutes long to upload onto my YouTube channel. I got all the way through it without incident, until I was ready to play it back to check and see if any editing was needed.

However, when I pressed the play button, there was no sound to speak of.

Going online, I found out the system of clicking "File", "Options", "Audio and Video", and then changing the audio devices.

I tried this several times, in several different ways, with no results.

I'd really like to know if it's a human or machine error, and a quick-fix would be appreciated.

Thank you very much.

Sincerely,

Originella

I have been using Windows Livemail for some years. I am aware that MS no longer supports it but lets people use it if they wish. 

Then last Wednesday 14 March 2018, I noticed that after the Windows Update, the contents of my Livemail folders (Livemail, Messenger, Writer) had disappeared. The folder names were left intact (in the Windows System folder) but empty. So why did the wretched Update do this? Don't they know that Livemail can still be used if you have got it?
So many of my folders, list of contacts etc are gone.

My questions:
1) Is it possible to reverse the Update and recover my files & folders? 
2) Can Update be instructed to leave Livemail alone?

I hope somebody can offer encouraging news.

I have trouble locating older emails in my hotmail and I went and consult the link in a previous post by another user and I am still unable to resolve the issue.  Below are the setting in my hotmail account.   I did not delete any folder or email.   Could someone please assist me with locating my old email please.
