I upgraded to Windows 10 for two days. Had problems and went back to windows 7. My Windows Live Mail 2012 went nuts. It added hundreds of emails I had previously viewed...back to my inbox. My first problem: Some of these emails will not delete. If I do eventually get some of them deleted...when I go to the "deleted items" and hit "empty deleted files folder" It asks if you want to permanently delete these files. I hit yes...and nothing happens. I now have 5900 emails in my deleted items folder that won't delete. I tried going to Programs and double clicking on Windows Live Mail...and hitting the repair option. It runs the repairs and says it was successful but...it is not! Also...I get some new incoming emails that says "Message Cannot be Found."

What the heck is going on? HELP!!
