软件大小：199K
【软件简介】：公路设计软件解密的二次加密文件。呵呵，zchlb朋友没说，我不清楚。
【软件限制】：必须注册
【作者声明】：初学Crack，只是感兴趣，没有其它目的。失误之处敬请诸位大侠赐教！
【破解工具】：TRW2000娃娃修改版、Ollydbg1.09、PEiD、W32Dasm 9.0白金版
—————————————————————————————————
【过 程】：
呵呵，注册画面一现出来就知道我又碰上Softsentry壳的东东了。^O^^O^
没想到作者“很怕麻烦”，算法一点都没加难，简直就是用Softsentry随便做了一下保护。
用TRW很容易就找到核心了，呵呵，再用Ollydbg跟踪吧，比较直观，还可以享受MP3呀。^O^^O^
