Just so you'll have a different source - I went to your site, into the secured area, and did not receive any warnings. I think the warning you have is something to do with browser settings or updates so that it recognizes the certificate, but I can't be sure. I have a system in my office and one at home, identical setups. I do the updates regularly to both, Same software, same everything. The office one never gives me those secure certificate warnings, but the one at home spits them out almost everytime I go online to order something. Go figure.
