Its you again
I'm not gonna answer your question but hope to help you in a way you will learn something
Remove your Mysql installation..... just do it! :-o to get rid off al your settings. Remove also the directory thats made by your last installation. Check if your my.ini is still present, ifso remove this also!
So now your totally clean
Re-install mysql start your winmysqladmin.exe in the bin dir of mysql, but dont do anything next with it
Download mysql-front http://www.mysqlfront.de/
Install mysql-front, start mysql front.
Now make a new connection with username: root and pw: root or if this not works keep your pw empty.
Next in mysql-front you can manage your useraccount and set your new pw. remove btw the user root@ so not root@localhost but root@ otherwise someone can connect to your db from another place
Hope this helps and you learn from it! Nexttime google a bit more before you ask things like this :-o
