Hi pals

I have been invited for the NERC aptitute test but I am having issues with my login.
I tried to login but could not due to password issues. Forgotten password.
I emailed them, they responded that I click on forget password and I did, an email was sent to my inbox .
I followed the process as specified...Clicked on the link but
Below is what usually shows....
