Boa Tarde

Esse erro seria do sistema emissor de notas (nfe 2.0)?

Bom dia

Tente desinstalar e instalar novamente. É erro no java, se persistir o erro somente a central da receita pode te ajudar. Esse telefone aqui é bem útil... 0800-170-110! Selecione a opção de nfe é bem esclarecedor!

O erro ocorreu porque eu acabei formatando o pc e perdi o certificado, Obrigado pela ajuda pessoal!
