the website does not change your password the most likely reason that you may be having problems is that you are incorrectly entering your username or password.
People make typos all the time, even when they are sure they are not, so here is what I suggest.
Click on the "forgot password" link under the login form. make sure that you have typed your email correctly.
When the email arrives Click on the link in the email, this will open the page to reset your password.
if you don't have a working link in the email very carefully copy the verification code, make sure you are not adding spaces on the end, paste that into the verification code box.
Open a notepad or word document on your computer and type your new password into the document. now copy that into the new password fields and confirm it.
Don't close the note pad yet, keep it open till you are ready to log in, now copy it again and paste it into the password box in the login box.
I always recommend a password manager like lastpass.
Please make sure you have tried all of these steps very carefully before you contact me which you can do by using the form below.
