Help me use Trellix Site Builder on my MacBook Pro?

I found this old post in support (http://discussions.apple.com/thread.jspa?messageID=2881754&#2881754) and am having the same problem (not being able to edit a website created with Trellix Site Builder, part of my Verizon internet account, because Trellix is not compatible with Mac only pc - I originally created the website when I had a pc). I tried the solutions they used to make it work - downloading and installing the browsers Internet Explorer, Netscape, and OmniWeb for Mac but those won't work on my 10.6.5 system. Any other ideas? Verizon and Trellix offer no help. Thanks!
