【破解内容】
我的一个朋友销售摩托车，让我设计软件，我哪有这个能力，于是在网上搜索了一下结果只有这个软件能下载，价钱是980.00元而且是打8折
建议大家都做什么摩托车销售管理系统挣钱那。我还发现网上摩托车销售管理系统很少见都是介绍和演示而且价格 昂贵。
废话少说进入正题吧。ASP脱壳简单，就不用讲了。
这个软件的保护形式为重启验证型的，一看就是注册码在一个文件保存或在注册表中保存。利用文件FILEMON查看
软件启动时调用DATA.MDB。于是打开看，结果MDB文件有密码打不开，利用软件还有30天使用期限提示下bpx messageboxaF9运行断下了。

总结：有上面的算法计算公式如下，我的机器码是-1074565927。
以我的机器码为例1074565927not+1=BFF36CD9xor11d7=BFF37D0E+1a85=BFF39793+BFF39793shl5=BE6689F3not+1=4199760D
转换成10进制-1100576269加上前面的-。
