My Outlook/Hotmail interface keeps deleting contacts.

I subscribed to Outlook Connector to start accessing my Hotmail through
Outlook. I'm having major problems with my Distribution Lists. They
disappear at random; the contacts in one or two of the lists double or
sometimes triple sneding me way over my contact limit. I've deleted them
completely (twice) through both Outlook and Hotmail making sure they both
showed no lists. I've retyped them all (twice) only to run into the same
problem. This time, Hotmail shows all my Distribution lists but one and has
triple-listed contacts in half of the others. In Outlook, I'm missing almost
half of my Distribution lists but have no duplicate listings in the others.
I am SOOOO frustrated with this as I use this for my home-based business and
we're talking about 800 or so contacts.
