thank for all your helping
now i fixed it by myself
and did remove the password back to normal
i do hope program team of Messenger Plus build or make a reset key in the future
or reset key(or uninstall) to original default of Messenger Plus (sure might need to do more work)(*which i meant uninstall it self it should work which isn't) as i really can't see one in it (*which i mean if in the future will find the way to make it happen and myself would love to help for that too as i try it on myself)
as this tools are already pretty good of itself
