点击仿真按钮就弹出错误信息，麻烦各位帮我分析一下。

我刚开始学ADS2009，我对照一本教材<ADS2008射频电路设计与仿真实例>仿真功率放大器，为什么我一点击仿真按钮就弹出错误信息呢?麻烦有遇到这种问题的朋友帮我解答一下，万分感谢！
错误信息如下：
   Error detected by hpeesofsim in dynamic device loading during netlist flattening. An incompatible DLL from “Visual Studio. NET 2003” has been loaded user-compiled model that was compiled using that compiler     (possibly for the “METMOS_FSL_ext”model). Because this can cause incorrect simulation results, the simulation is being terminated.

你用的什么模型库，你用ADS2008试试
