first of all, do you have a db? =)
if you do then is it on localhost?
if it is then make sure ur username and password match (check it in winmysqladmin and db.ini)
if they do then :
u might have to GRANT ALL PRIVELAGES (forgot the whole command, if i find out ill edit to include it in the post)
if that doesnt work either then try setting ur db address in db.ini as 127.0.0.1, if that doesnt work either, then ur network address
if all else fails, then ur screwed
good luck
