Boa tarde Francieli

Possibilidades:
Normalmente ocorre esse erro quando o Java esta desatualizado.
Firewal Bloqueando a permissão.
Permissão de Pasta , na pasta do emissor.
Antivirus - tenta desabilitar
Baidu- Sempre que o Baidu esta na maquina temos problemas com operações

pega os arquivos da pasta NF2 e transfere para NF310

Se não tiver outra forma tenta desinstalar o java e emissor e reinstala ...
