使用BMDThread控件，程序编译出错(20)

我下载并安装的BMDThread控件，但在编译其自带的例子时出现了如下错误：[Error] BMDThread.pas(54): Undeclared identifier: 'TFileNotification'[Error] BMDThread.pas(55): Undeclared identifier: 'TEventNotification'[Error] BMDThread.pas(98): Unsatisfied forward or external declaration: 'TBMDThreadBase.GetRuning'[Error] BMDThread.pas(100): Unsatisfied forward or external declaration: 'TBMDThreadBase.ReportStarted'[Error] BMDThread.pas(101): Unsatisfied forward or external declaration: 'TBMDThreadBase.ReportTerminated'[Error] BMDThread.pas(102): Unsatisfied forward or external declaration: 'TBMDThreadBase.AddMe'[Error] BMDThread.pas(103): Unsatisfied forward or external declaration: 'TBMDThreadBase.RemoveMe'[Error] BMDThread.pas(107): Unsatisfied forward or external declaration: 'TBMDThreadBase.Start'[Error] BMDThread.pas(108): Unsatisfied forward or external declaration: 'TBMDThreadBase.Start'[Error] BMDThread.pas(109): Unsatisfied forward or external declaration: 'TBMDThreadBase.Stop'[Error] BMDThread.pas(110): Unsatisfied forward or external declaration: 'TBMDThreadBase.Suspend'[Error] BMDThread.pas(111): Unsatisfied forward or external declaration: 'TBMDThreadBase.Resume'这是怎么回事，应该如何解决。
