紧急求救！！！！！

the model was built in an older version,and therefore it must be compiled,updated and then re-compiled. it is possible that very advanced modeling techniques may not be successfully updated;therefore it is recommended that you save the updated model with a new name.这是怎么了？？

这个是你下载的模型是之前的老版本，在新版本中打开就遇到上面的问题。老版本都是需要编译的，而现在新版本是不需要编译就可以运行仿真模型的。嘿嘿！
