1、PEID查壳，ASPack 2.001 -> Alexey Solodovnikov壳，很容易脱，略过，
脱壳后的程序是用Borland C++ 1999编写的
2、OD载入，查找错误提示信息“Your registration code is invalid.”只找到一处错误提示。双击后在代码段头下断

算法小结：
1、用户名位数大于3位，未参与注册码计算
2、第2、11、40-44位分别为0、Y、P、2、I、1，24位是0-9的数字
3、先将注册码第2位替换为“#”，然后和字符串“1z1h+2a0n-0g8y*9a1n|”循环运算，算出第12-19位的注册码
4、替换后的注册码经过16次循环，得到字符串“mxaxaxaxaxaxaxax”，再连接上“ZY”，即“mxaxaxaxaxaxaxaxZY”
5、字符串“mxaxaxaxaxaxaxaxZY”经过16次循环得到25-40位的注册码
6、其他位的注册码参与运算但未进行比较，所以仍是你原来输入的相应数字

算法比较简单，就是循环次数太多，要有耐性
由于注册机在制作过程中出现一些技术问题，（第2组注册码能成功算出，但第一个有些问题）正在调试，成功后再发
送两组可用注册码：
