Erro certificado digital A3

Pessoal estou com um problema no certificado digital A3, quando envio a primeira nota funciona corretamente e quando mando a segunda gera um erro, ate parece que fica algum tipo de sujeira, se algum poder me ajudar agradeço.

Este envio de nota esta funcionando como serviço.
