Emissor de NFE gratuito 3.10.86 - Falha ao validar a assinat

Prezados, boa tarde.

Estamos tentando, sem sucesso no dia de hoje (15/07/2016) executar o software Emissor de NFE gratuito 3.10.86, com o erro abaixo:

JNLPSigningException[Falha ao validar a assinatura do arquivo de acionamento. A versão assinada não corresponde à obtida por download.]

Já testamos em várias máquinas diferentes, com versões do Java diferentes, com versões do Windows diferentes e ocorre o mesmo erro. Entrei em contato com outros escritórios vizinhos que o utilizam e informam o mesmo erro. Alguém sabe dizer se ocorreu alguma anomalia geral no acesso? o Conteúdo do emissorNFe.jnlp listado no erro:

Boa noite, amigos.

Estou com um problema não consigo validar nfe no emissor gratuito do estado de SP.

Da a seguinte mensagem: Element has xsi:nil attribute but is not nillable in element infNFe@http://www.portalfiscal.inf.br/nfe

Já procurei nos forum anteriores e não achei erro igual a este.

Desde já agradeço atenção.

Obrigado.

prezado,

Poderia postar o XML gerado pelo emissor para que validassemos? esse erro INFNE pode ter diversas causas.
A melhor forma de analisa-lo é pelo arquivo gerado pelo software emissor.
