I am having trouble with windows live mail. I found I was not receiving a lot of emails sent to me.  I did some test emails and they are not coming in either. I am still receiving some emails 

Then when I checked the outbox 4 of them were sitting there.  So they did not send.

I contacted my email provider and after many attempts to fix the problem were not able to. They even came into my computer remotely.

Would it be wise to uninstall and reinstall? Thank you
