My laptop Toshiba does have a nnumber key pad, except that I have to press a certain function (alt or ctrl can't remember) to activate the number pad. You might want to look at your laptop manual how to access the keypad.
To be honest I'm a bit fed up now as I only joined to get this trainer and I can't get it to work after hours and hours of trying everything I can think off including a full uninstall and reinstall of the game and steam.
Are there aany other trainers out there because I am going to need another option I think??
