先用OD载入这个文件，查找字符串“isvip”找到后，在它上面的“register.ini”语句上面的call语句下断点
21987044 . E8 C882FFFF CALL XLUser.2197F311 ; 在此处下断点 ，F7跟入

此时就用OD载入“Thunder.exe”，F9运行迅雷。在这里中断后，F7跟入。
21987044 . E8 C882FFFF CALL XLUser.2197F311 ; 在此处下断点 ，F7跟入
进入call子程序后，我们找子程序的末尾处，找到后，找最后一个跳转语句，在找跳转语句上面的call语句，在call语句上面下断点，然后F9，待到程序中断后，F7跟进去。
