Erro na transmissão da NFe - Versão 3.10

Bom dia,

Amigos estou com muita dificuldade em ajudar um cliente para emitir uma NFe pela programa emissor de NFe da SEFAZ SP.

Versão do programa: 3.10.31 - (22/01/2015)
Versão do Java: 8.31
Windows 7

Estou muito preocupado. Por favor, alguém consegue me ajudar?
