you have to click on forgot password. you will get an email and then you have to change your pw. then it should be unlocked. the day you signed it at the pool, do you received an email from this pool ?
I did reset password, i got the link, i changed my password, it said "password changed please log in", i tried to login and it still gives me "Unable to login: Account is locked. Please contact site support." which still is saying "This product comes 'as-is' without any warranty. Please check the Apache License, Version 2.0, for details."
