i  create a new Compound. drag a mov file to the workspace , connect media file to preview. there is a blue screen with some word: 'NOT GENUNE 0100' . i  deactivate ,activate, uninstall ,install some times , all this actions are no effect.

aximmetry里建了个空合成，拖进一个视频文件，连接一个输出，预览窗口上，多了层半透明的蓝幕NOT GENUINE 0100。反激活、激活，卸载重装好几遍，还是不行。

问题已解决，重装Windows，，，，这是官方销售的推荐步骤。
