email "stuck" on server – unable to download

An email has been trying to download for two days now.  In addition to this "stuck" email, I keep receiving emails I have already looked at and deleated each time I open my windows live mail.  Even when I push "stop" to stop downloading the email,  the program keeps trying to finish downloading the "stuck" email.  I let this go on for an hour with the email still not downloaded.  I'm afraid my computer will overheat!  Please help me get this email out of "cyberspace limbo"  I am not using Windows Hotmail Live - this is happening on my Windows Live Mail account.
