I bought the steam Deluxe Edition yesterday cause it had a 75% sale, but when I went to run the trainer I found when I hit the F1 key to activate it keep repeating Trainer Activated in the background, and I mean it repeated it over and over. If you are having this issue too this may work for you too. NOTE I tried every trick they suggested.
1. I have win7 so made admin rights, right click Trainer, Options, Compatible tab, Run as Administrative.
2. When playing Civ5 have steam in off online mode. Open Steam, click in top left corner Steam scroll, select Go offline. Steam well restart, (If you want to play in online later select steam, go online)
3. Run trainer, gun game, and it should stop with that Activation repeating voice.
