Does the language you translated it for have an icon that appears?
The icon should light up when the translation is ready. If you click it, it will show the translated version. If you click the icon for the original language, you can switch back.
If the icon doesn't light up, go to the Options tab and select Translate This Page. Make sure the other version is selected. If you clicked a flag or used this form to create the translation, it should be selected automatically. If this didn't happen, there might be a bug.
