Got some issues when sending post using WLW or by Email

When I send a post by WLW I get an error on WLW as you can see on printscreen. The post it's well send but there is this error and it's not autopost to social network like Facebok and Tweeter.

When I edit and save the change I got this error message ;
Error validating access token: Session has expired on Thursday, 03-Apr-14 00:57:05 PDT. The current time is Tuesday, 22-Sep-15 08:50:10 PDT.

Another thing, the first picture of the post dispear from the content and go as main picture.Is it normal?
Is it possible to keep it on both main an inside the content?

Thanks in advance for your help
