I have used my email address as requested. I have copied and pasted the password supplied in my email to ensure getting it exactly correct.
Sometimes browsers will insert hidden characters that affect the password, so copying and pasting won't always work. The best way to get around this problem is to carefully enter the password by hand. Another alternative is to first cut and paste your password into a text editor such as Microsoft's "Notepad". Notepad, and other text editors, will strip away all hidden characters. You can then copy and paste the plain text password from Notepad.
