Original title: cant delete email

I'm using Live Main in windows 7.

There is an email i can not delete. I've tried repairing windows essentials,  I've deleted it from my server's website. I've also right-clicked it and marked it as unread. Nothing works and any help would be greatly appreciated.

When i try to delete it live mail freezes and i get an error message with these details:
