Are you positive that new native trainer has the updated bypass with it? WashedOut has been having problems with alot of people lately from alot of comments about it.
Make sure you have dinput8 in there and try downloading this scripthookv from Kr0wnz click me
Report back with information on what happened. Also try only kr0wnz by it's self, remove other mods. Make sure GTANative is in there.
