Rezinjector not found PV_M9.DTX
i have searched all over the internet and cant find an exact place where im supposec to inject the PV_M9.DTX all i have seen was to inject it into GUNS_SND_MELEE.rez or GUNS_M_PV_MELEE.rez i have tried both but it kept saying " Status: not found ". and then i tried running the rezinjector as admin to see if that was the problem..it made no difference. thank you for the help.
