Unless I missed it, something that needs to be added to the general troubleshooting post you made, Neo7, is that these latest trainers in Windows 7 require you to right click and "Run as administrator" in order to function properly. Strangely, I have only had to do so with the newer, fancier looking trainers, although it may be because of how specific games have operated that I have used trainers for.
In mine, I could still hear activated, but the options when activated does not ring 'activated', but I do see the cheats in effect, e.g. $, energy. Just a suggestion, try a obvious/riskless option like $ and see if it really works?
