我照着《挑战soc-基于nios的sopc设计》上的例子生成了nios系统，加上引脚后，编译出错。错误信息是：
Error: Can't find valid feature line for core 6AFA_1001 in current license
Error: Can't compile design containing encrypted file C:/altera/work/niso_system_module/sopc_parameters_0.tdf -- current license does not allow this file to be opened
Error: Node instance "the_sopc_parameters_1" instantiates undefined entity "sopc_parameters_0"
Error: Quartus II Analysis & Synthesis was unsuccessful. 3 errors, 16 warnings

我用的license是在这个网站下的crack。在安装crack后没有看到6AFA_1001 ，请问高手这该咋解决？[em16]
