Windows 10: Issue with WLM..... error message

I was messing around with my Intel Compute Win 10 Stick so much so I had to do a Reset and keep Nothing.
All is fine except WLM.
I tried to reinstall WLM using my WE 2012 Offline Installer which worked for me many times since MS stop supporting WLM. But this time, something went wrong. It said unable to install.
But when I went to check in Programs and Features, WE 2012 was listed.
Anyway, I went to Start menu and found WLM, pinned it to taskbar.
However, it can receive but not send.
Error message...……





I have no idea what it says.
Can someone help ?
I can use my gmail for now, but would like to fix the problem as I have been using WLM since day one.

:)

 

Skype instant messages (WLM is dead, MS account merged)

Thank you! I logged us both out on every device and logged back in using our original id's, sadly that didn't work. Nobody appears online in the hub on WP8. I was able IM her via Outlook.com though.



My im's via Outlook appear under my Skype name on her PC. I can see the test messages across the board, except for WP8.



A reinstall of Skype on WP8 would no effect on the messaging hub I suspect.

 

Skype instant messages (WLM is dead, MS account merged)

For my explanation to work:

• The Primary Microsoft account that is set up on the phone must match the Microsoft account that is linked through your wife's Skype account - a secondary WLM Microsoft account is not integrated into windows phone messaging hub.
• Only messages that are exchanged between the WLM contact in Skype will be displayed in the windows phone messaging hub
• You must log into Skype with the WLM login and NOT the Skype login.

If you don't see your wife as online after she's logged into Skype that's another issue that needs to be solved. Here are some things to review:

Go log in to your primary Microsoft account (the one you use on your phone) from a computer.

When you get to the Outlook hub, click the small white messaging icon found in the blue bar at the top of the screen. This should log your Microsoft account into Messaging (if you aren't already logged in).

Click the "Start new conversation" dialogue box and you should see a list of your contacts that are online. This will include any contacts that are linked via Skype or Facebook - do you see that your wife is online there?

Send her a message while you're there. Does she receive your message?

Now, go log in to your wife's primary Microsoft account (the one that she has linked to her Skype account).

Click the small white messaging icon found in the blue bar at the top of the screen. Click the "Start new conversation" and run the same test that you ran on your account.
