Well I haven't been able to get float to go either which is kind of a drag since it is the cheat that is most useful. I've tried on my bought version & the iso demo - result same both times. No sound from machine no matter how I press f5. In the air or on the ground dante remains oblivious the abolition of gravity in his personal space. I dunno if it is me thinkin negatively or the trainer but I don't seem to be able to jumnp so high when trainer is on either. I'm runnin 7 x64 be interested to know what OS those who havemanaged to toggle float on & off are usin. I'm also using a 360 gamepad n I did wonder if usin that made the game block out the Fn keys.
