Updated link in Dreamweaver doesnt show online...

My company has a link on all emails that takes customers to our online catalog. The link is www.ari-hetra.com/catalog
Just a few weeks ago i updated the catalog, and have a new link to the new one, (it has an orange cover, old one had purple) and i put that into dreamweaver, and it shows the new orange one in dreamweaver. so far so good. i took the old one off the server, saved the index, and reloaded it onto my server. However, when i type in the link in my browser it keeps showing the purple catalog, even when i hit "shift+refresh" to clear all the cache/cookies, it is still the old purple one.
So i've taken it off several times, reloaded it several times, when i click on the index.html in my documents it pulls up a page in my browser for the orange one. So the coding is right i'm assuming, and its on the server and live,but theres just something missing to the puzzle that i am not understanding. Any suggestions?
Thank you in advance.
