[charlesbrent911]

im currently using 3 computers to play project 1999 classic scars of velious 1,
those ips are:
192.168.1.65 username removed
192.168.1.72 username removed
192.168.1.73 username removed
email: removed , please contact me here, if u can help me as soon as possible

I logged in fine on removed and removed, the final account and ip # isn't logging in, says a block, as if ur boxing on 1 computer, the other 2 computers are fine, as a I know, all computers are assigned a different ip #, up logging into the internet service provider, maybe its a identity theft of ip # ???? or possibly an error on the network card???? any idea if ur site can solve this problem for me, ive already brought up my command shell, where I checked netstat and ipconfic, those ip addresses are each different in everyway.
thanks
