You have to check the configuration of the MySQL database and to make sure that correct credentials are used by your Qt application (or library). If you have no idea how to do it please use google and you will easily find numerous free tutorials :)
You have two options in order to retrieve your username or password.
1)Re-install MySql and reset new ones
