The 'Forgot Password?' option doesn't send the email

Hello,

I have been using my account for many years without any problems. However, suddenly, my login attempt says that I have an incorrect username or password. I am certain that I haven’t changed my credentials.

This is a paid account associated with the email address emservpn2@sit-cba.com.ar.

I tried to use the “forgot password” option, but I haven’t received any email.

I hope you can help me resolve this issue.
