У вашего броузера проблема в совместимости с HTML5
*UPDATE* This has been patched out of the game.
There is no way I know of to get in the system without having an active trace put on you, but you CAN intentionally start another 'trace killer' mini-mission at any time without losing your progress on the server, even when you already have admin rights, effectively giving you infinite, if stressful, time to do what you want on the server.
P.S. HOLY HELL I CUT THAT CLOSE! My recommendation is to just start another failsafe minimission when you're done with the server, rather than try and fix your IP at the same time. It is more fun my way though. :D
