If you want to play around a bit you may find the account key in the cookies of your browser.
When you log out here on the web pages in "Your account", the cookie will be deleted. Trying to access "Your account" again then should lead you to a page where you can have your account key sent again to your email address (if you give the same that it is in our database).
Regarding the "100% WU" you may look at the thread "WU not finishing". Should be fixed with the new apps.
