Install 5.5 Assistance Needed

Hello,

 

New user to Mysql 5.5. I did the complete install, and I entered a
username, and password for this service.  The install went smooth, but
when I try and start working on the command line, I get the following
error? There is no readme inside the install folder? Can anyone give me
some advice?

 

 

C:\Program Files\MySQL\MySQL Server 5.0\bin>mysql -u admin -p

Enter password: *****

ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using
password: YES)
