We can't do much troubleshooting without the complete error message.
No, you have not followed instructions. Look at Gary's reply and follow
those instructions. Even better than that: create a new thread for your
problem and describe the problem; it is critical that you provide the entire
error message exactly as it is, except for email addresses, REPLACE the part
BEFORE the @ so spammers don't get the correct email address. Don't change
the part of the email address after the @.
