Hello, again!
A link about this error.
Basically, either your user/pass combo is wrong (which you checked) or your user/pass does not have the proper privleges in MySQL. Try the following:
Code:
START->RUN->CMD
cd c:/mysql/bin
mysql -u root mysql
GRANT ALL PRIVELEGES ON *.* TO username@localhost IDENTIFIED BY 'password' WITH GRANT OPTION;
quit
~Gandar
Let me know if that clears it up.
