The FX-CurrencyConverter plugin is a total vanity plugin. When you try to see the money conversion a large window pops up with the developers advertising. I would recommend the plugin "WordPress Currency Exchange", but, I had to fix some serious code issues to get this plugin to work. I sent my fixes to the developer in July but they never respond or posted the fixes. So, if you want a working copy of WordPress Currency Exchange feel free to contact me at mymarketer.net/contact. Good luck.
