关于ispLEVER starter 2.0的问题

我前些天下载了ispLEVER start 2.0免费软件，并安装了全部4个部分。然后按要求下了许可证，并放在按要求存放了相应目录，然后 可以运行ispLEVER,Synplify软件。可是一运行LeonardoSpectrum时就出现license不对的情况，请问这是什么原因。
而且我发现当我运行ispLEVER中的Function simulation时出现下面的错误提示。也是和LeonardoSpectrum的license有关。

 特向你请教，不胜感激！！！

license.dat文件有问题，或者autoexec.bat设置有问题。
