I was just approved as a new user but the assigned password does not work.

You can use the Lost Password tool on the main page once every 24 hours to have a new password generated. However, there are no known bugs with this feature. Make sure you've spelled the password correctly (it is case-sensitive), and if you are pasting it directly, avoid pasting a leading or trailing space character.

Idid try to use the new password and it still does not work.

What exactly is the error message you receive?
