Sync WordPress Users to Interest Groups

My autochimp also does not sync my users to my mail chimp mailing lists. I spoke to mail chimp and they referred me to wordpress as they determined that everything is working properly on their end. I have two problems that I was referred back to wordpress for. My analytics 360 gives me an error code and no statistics unless I go to my google page to pull up google analytics and my subscribers are not being sent to my mail chimp lists. I have over 100 subscribers not on my mail chimp lists for no known reason.
