I'm working off of a mac. totally frustrated because i wanted to put my
website up tonight. by the way, it's a flash website of my online portfolio
work.

try using the ip address. make sure dreamweaver or your ftp program has access through the firewall, and check with your hosting provider the correct ftp information
