I've been using ejunkie for some time now and I do most of my work on mac and everything seems to work just fine on both safari and firefox... today I decided to test everything on my pc and sure enough ejunkie just doesn't seem to work with IE nor firefox! I don't know what to do to get this working!

I checked your site in IE 7, Windows Vista and it works fine. Can you please let me know what happens when you test it?
