I've installed the plugin, and renamed the folder "curreX" as the other thread mentioned. I see the plugin on my sidebar when it's in HTML mode, but nothing happens when I click the "Convert" button. Doesn't matter what currency I select - nothing happens when the button is clicked.
Furthermore, I can't get the plugin to work in Flash mode. All that appears in the sidebar is the Adobe link to get Flash. I have Flash installed on all my browsers, so I think there's something in the code that isn't passing.
Please help, because I think this is the most useful currency converter I've seen so far.
