That login is for 1.5 only and has been discontinued for 2.5, this is stated in the Emma Smooth download section:
This package includes the modified version of tab show used on Emma Smooth. Unfortunately, due to compatibility issues the modified login module shown as a drop down box on the demo could not be converted to 1.6+. You may still use the default login module in any of the template positions such as the right column. All other modules used on the template demo can be downloaded from their categories in Club and Free Extensions.
