Have been using WLM (2012 version) for some time without issue. 2 days ago, most ( only one or two random emails appear properly) new mail began to appear in the message window blank - no "subject" and no "from" info from multiple email addresses ( all AOL ).  A line appears for each new message but no info is displayed - just the envelope icon at the left of the line and a time stamp on the right side of the line and no reply/forward option on top. The time stamp is always the moment the message was downloaded to the computer. When I hover over each message line, the popup window shows no subject and the file size is 0KB. mail loads properly in the reading pane and if double clicked to open a new window ( with subject to/from info) All mail displays properly in WebMail and on my phone. I have removed and added the email account multiple times and ran Microsoft update and added all theupdates and still same result. 

running on windows 7 and wlm 2012

any sugestions?
