All emails in Live Mail 2011 are scrambled or garbled

I use LiveMail 2011 to read and send Emails. It has just opened with all Emails scrambled / garbled .... here is a screenshot:

ALL Emails are like the view on the right hand side.

I tried restarting the computer but it did not work.

I tried a system restore but that also had no effect.

I wanted to reinstall LiveMail 2011 but the link took me to a Windows 10 page.

Questons:

1) If I reinstall LiveMail 2011, will I loose all my emails?

2) If I backup my emails now....will they be saved garbled?

3) Where can I get a copy of LiveMail 2011? (I do have my Windows 7 Disk).

4) What other options do I have?

Thanks for any input!
