Hello, I have a problem when logging in, I get that the password is incorrect.
I enter the "forgot my password" section and enter the email but I never receive the email to reset the password. I had to create a new account with another email to be able to create the report in the forum, can you help me?
My oldusername it´s Mathiwooow22.
