显示2026 实际是永久!
注意事项
注意，2024.2 之后的版本，若初次安装，会提示选择所在区域，如下图所示，如果选择了 China Mainland，会反复跳出激活码并提示无效，原因是新版本会拦截 .cn 域名，导致许可被吊销，所以，千万不要指定区域！！
如果是老用户，则可以在设置菜单中来更改（一定要更改）：
显示Key is invalid 或者打不开
-
只复制了ja-netfilter.jar，或者文件夹
/jetbra被删除。/jetbra要copy一份，需单独存放，且放置的路径不要有中文与空格，以免读取补丁错误。以后这个文件夹不要动 -
显示了
-
/jetbra文件夹路径中包含空格和中文 -
检查复制激活码时，是否缺漏
-
还不行，则回退版本，退到1.x版本
