Lost Contacts application

[aguarderas]

Hi, i can't open the contacts icon for my galaxy ace plus. I can only add contacts through the phone icon, but it only allows one phone number and no email.
If i go to manage application the icon contacts an orange icon is there, but i can't do anything with it, i try to edit , double tap and nothing.
