A general answer for solving these kinds of problems is using the Selenium IDE. From here, you can manually click buttons on a website and have the Selenium IDE (a Firefox plugin) record your actions. From there you can File > Export Test Case As... and choose whatever coding language you want.

Selenium IDE Firefox plugin version 2.9.0 http://release.seleniumhq.org/selenium-ide/2.9.0/selenium-ide-2.9.0.xpi

EDIT: Sometimes you might actually be finding the correct element, but the webdriver tries to find it before it's there. Try adding this line after you create your webdriver:
In Python:
driver.implicitly_wait(10)

This tells your webdriver to give itself more time to try to find the object. It does not add a 10 second wait, but says keep looking for 10 seconds. If it finds the element before 10 seconds, it will continue on as normal.
