Thanks for the trainer. I'm glad to have it, but a couple of the options don't seem to want to work. I'd beening trying to get float mode to work. Even saving, closing, and restarting the game as previously suggested to no avail, but finally as if a fluke I got it to work. The question now is how I do turn it off without having to restart again. I tried hitting F5 again but it didn't do anything. I don't know if it means anything, but I noticed when float mode finally worked the trainer didn't do the usual "activated" or "on" sound your trainers usually make when an option is toggled. Anyway, I'm still grateful for the trainer. You might want to look into though since it seems I'm not the only one not able to get all the options to work like the Red Skull option. I tried restarting the game a few times. No dice.
EDIT NOTE I haven't been able to get float to work again since.
