BuddyPress.org

im using a theme called social marketplace by buddyboss, it comes bundled with buddypress.. they have these hideous login and register overlays that are cool in theory but i dont know how to style them in CSS… (im a noobie) so i went into the theme settings and shut them off.. now my login page goes to /wp-login and my register page goes to /my-account

my account page still looks like the buddypress registration form.. when it should infact look like this

i use a plugin called wc vendors.. that say they hook into the my-account page ( whatever that means)

i just want to get my login and register pages looking similar i cant seem to figure it out.. thanks
