美国签证ds160填写过程系统错误求助

已经上传完照片了，这个时候 只要一点 下一步review，或者点保存成文件，系统就报错并自动退出。错误提示如下： Application ErrorAn unexpected error has occurred while processing your previous request. The error has been reported to the site administrator; no further action is required. To retrieve your DS-160 application, please enter your Application ID. 快一个礼拜了，试了各种电脑、浏览器，不一样size的照片 都不行，还让朋友帮忙从美国填，都是一样的错误。怎么办啊
