i made a free vent using my ip adress, but then i accidentally delted my username so it made the vent get deleted! i cant get back on because i cant get to the netgear smartwizard thingy to change the ip address, because the ending which used to be .3 changed into .6!

when i type in the router IP it just tells me that its already being controlled by the one called .3 )_) which WAS my comp! idk how it changed ;_; and idk how to get my vetrilo back T.T please help me!
