Another Problem Now

... with navicat lite which is my db editor i open all the trinity programs and the apache and my sql and i try to make a new connection and i get an error saying
1045 - access denied for user 'root'@'localhost' (using password NO)
i dont know if this is me being noobish but o well i would like to sort this as i would like to add custom items and weapons soon ,,,
also is the core meant to close by itself once youve clicked it or is meant to stay open because mine auto closes i donno if that i right or not but anyone who can help me with these probelems ill +rep them

btw it stays up longer when i push ctrl+c but i cant add an account untill it stays up or navicat works right with the server ... either way let me know how to get the problems sorted thanks
