Nokia Communication Centre

Hi, I'm having a problem with Nokia Communication Centre. It seems the problem is in my phone, 7610 Supernova. When I open Contacts/Contatos in Nokia Communication Centre, it opens an error message and the software can't gather my contacts. The error message is something like "Error while updating contacts, verify if the phone is inactive and try again" (in portuguese, it is "Falha na atualização de contatos. Verifique se o telefone está inativo e tente novamente"). It's strange because there is no proble with the Calender/Calendário nor the Messages/Mensagens. Can anyone help?
