Okay, you guys obviously aren't reading my guide.  Note the section about your problem.
Note: If you get an error when typing the grant all privileges line:
1) Make SURE you copied the line of code EXACTLY as written and changed username/password. (you need the ''s(apostrophes) around the password. 'example' not "example" or example.)
2) Try opening a command prompt. Type:
then type
	Code:
	mysql -u root mysql
 
And proceed to type the grant all privileges command again.
------------------------------------------------
It's clearly stated in a different color, including code examples, on how to fix your problem.  
My adivce, 
READ THE GUIDE THOURGOUGHLY!!
