Can't control computer I'm connected to

[Prokadon]

I've installed both v6 and v7 and both don't work.. I have to say .. it worked before and I think it has to do with the game I'm running on that computer. I cannot do anything.. I see the custom cursor that is being used but I cannot click, drag etc etc only thing I can do is point and the computer also doesn't see what I am pointing at.

Some idea's?
