I am trying to activate my account and entered a new password. I get a message that there is an error with my password but it meets your criteria.

You are probably getting this error message,  "Your password must contain at least 6 characters. It should include numbers, punctuation, and both upper and lowercase letters."   

It is likely that your computer is configured to block a pop-up window.  You may notice a warning about blocked pop-up windows near the top of your computer screen.  You might want to disable this feature for this transaction or try again using a different browser.
