Good Morning Andrea,
Thank you for your question. The only real requirement is that the password be between 6-16 characters long. We usually recommend an uppercase letter and a number or symbol, but it is not required. However it is definitely going to be case sensitive so if you used uppercase when you made it, you will have to input it the same. You can find out how to reset your password at I forgot my username or password. If this still doesn't work, please give us a call. Our US contact center is open Monday - Friday from 6am-6pm PT or Saturday from 8am - 6pm at 800-518-5689.
