I cant list my CustomPress posts from my menu link

I followed the tutorial for CustomPress and created post Type Atracoes. I can post on it, and the customfields are working, but i cant make a link trough my menu to a category from my custom post. Example, if a click on any from the created ones (Clicking on Menu item "Atracoes Turisticas" and then from Bar Until Museum) I get a 404 page like this http://paratyvip.com.br/?atracao=barco-de-aluguel! What am i doing wrong? Suport access is granted on this site!
