我在用例子下载时出现了这样的警告：

    File full_featured_time_limited.sof contains one or more time_limited megafunctions that support the openCore Plus feature that will not worke after the hardware evaluation time expires.Refer to the messages window for evaluation time details.

好象是说功能模块过期了，请问怎么看是什么过期了，怎么样能解决这个问题。
