[182Gamer]

Hello friends, I'm having trouble with my recordings with DxStory, always used the program to make the recording of game plays, however recently had to send my computer assistance to perform formatting and other procedures, and he came back now, so again I had to set my DxStory and after setting I tried to write PES 2016 and Diablo 3 put my program is not recording my audio and my game play, only thing my DxStory this recording is audio play, video is all black and I can not hear me, only thing that really is in the file is the audio of the game, I looked for some tutorials on the internet however did not find anyone with the same problem, so I ask some way to solve my problem, thank you, Waiting for answers
