Login problems can have a number of different causes. These are usually either forgotten or incorrect username and/or password or you simply don’t have a user account.
If you have forgotten your username or password, you can arrange for a reset link to be sent to your registered email address by following the link on the login page or click here http://elearnwithnca.co.uk/component/users/?view=reset
If you are sure your username is correct and you believe you are entering your password correctly, it may be that you have a sticking key or the Num Lock or Caps Lock are on. Try typing your password into a text editor (e.g. Notepad) so you can see what you are actually typing. Remember that passwords are case sensitive.
When copying passwords from email messages, it is often the case that you will pickup a space character at either the begining or end of the password. Please be careful to check that this isn't the case. Try pasting it into a plain text editor such as notepad to see what you have copied.
If that still doesn’t help, you can use the forgotten password link to arrange for a new password.
