It may be your computer Joyce, we need to first though eliminate all other causes for this.
I want you to attempt to reset your password ***** by using my link below.Click me to view
Once you have reset the password, use this new password ***** sign in.
I can see you are a first time user to the site. What we do here is either a question and answer type of conversation or remote support where I would actually connect to the computer and have a look and fix the issue if possible.
Remote support can save a lot of time if you are not comfortable performing repairs yourself.
I will send an offer through for remote support and should you accept I will connect and see what is going on and fix the issue. Otherwise we can continue to talk like this but I will need to ask a number of other questions and try and walk you through some steps for repair.
Both options are 100% guaranteed by the way. Remote is just quicker and avoids the risk of you making a mistake and doing something wrong.
If you want remote click get extra help. If not simply reply to me.
Let me know the results please
