This does seem to work most of the time so let's hope you have a backup of what you can't lose.

After working for months/years, WLM will no longer open... the icon simply rotates - nothing else happens. I have tried all of the suggestions found online and none have worked i.e. looked for KB2454826, it was never installed, installed latest service pack, everything. I would be willing to uninstall/install again but I do not want to loose my contacts and emails; and not able to save them as I can not open WLM. I can not even stop it from updating from my email provider as I can not open it. Help! Any suggestions welcome.
