Hotmail junk email

My junk email box keeps refilling itself, not only with junk messages but numerous copies of the same email  Even after I empty it (or delete them), it just refills and then I get a message saying I have gone 'above my quota" and I can't receive any more emails, even in my inbox.

I am still using Windows Live Mail which is far and above my preference.

Any help would be appreciated.

Thank you.
