After upgrading my Windows 7 Pro 64 bit disk to Windows 10 Pro 64 bit I have been unable to open any emails in Windows Live Mail. All my email folders and messages are present, but whenever I try to read an email I am told "a problem occurred. Please try again", but trying again makes no difference.

I used the repair option in Programs and Features, and was told the repair was successful, but it wasn't because the problem persists. I also tried uninstalling/reinstalling Windows Essentials, but that made no difference either.

URGENT advice as to how to solve this problem would be appreciated.

Thanks and regards,

Roy
