windows mail live has stopped working

Need help or suggestions on how to get the wml working again, as it suddenly stopped working
Tried the repair process a few times, updated to the latest windows essentials as well.
Tried to do the complete folder erase and reinstall. No change.
I had this update happen prior wml stopped working:
Platform Update for Windows 7 x64-Edition (KB2670838)
wonder if there is any relation.

thanks for any input

Thanks for your reply.
But this has no relation to my request.
Can't open windows live mail at all.
Looks like all features of windows essentials have stopped working.
when launching it, the message windows mail live has stopped working appears
And any repair process doesn't seem to do any better.

Yes there is a relation with that kb. Ms update, reported on windows update site others are having problems with WLM
Uninstall the update and all should be well
