Hey, someone please help me out.

I used to have lime wire, but recently i purchased lime wire pro for turbo charged downloads. However i can now not play pc games, it still lets me download them ok, but however when i go to install/run them limewire displays a message, "Limewire will not lauch the specified file for security reasons" and this is not just with the odd file, all game programs now display this problem. Does anyone know how to avoid this, or how to change some options to stop this? please reply, thank you.
