I have been using Windows Live Mail software for years now. Suddenly, today, I get a pop-up message when I try to send emails. It states that I don't have a Digital ID, so my message won't be saved in my "Sent" folder. It does it for ALL messages I try to send.

I only changed one setting yesterday (or the day before). I unchecked "Remember Password", so I have to log in every time I open the software. NO OTHER SETTINGS HAVE BEEN CHANGED. I had my settings this way when I first got the software and this message never popped up.

While writing this, I actually followed through with sending an email and it gives me another pop-up message stating that the recipient's Digital ID is missing.

1. Why is this suddenly happening?

2. Why would an individual personal user (not a business entity) need to purchase a Digital ID?

3. Don't tell me to re-check "Remember Password" as your resolution to this issue, as I tried that and it still does it after I closed and re-opened the software. It may require a reboot of my computer, though as I probably closed and re-opened the software after I unchecked "Remember Password" yesterday and it didn't do this until after I booted up my computer today.

4. Don't tell me to get a Digital ID as your resolution to this issue.
