When I'm trying to set up my xbox it says xbox live cannot be found. It does a troubleshoot and says wires are correct, IP address found, DNS thing found but xbox live not found. I've rung xbox up about 10 times in the past 24 hours and they've responded by telling me someone will ring back. not one person has rung back. i'm using ntl, with a crossover cable going straight from the set top box into the xbox. i'm getting sick of all this, plus my old, modded xbox won't even do link up anymore and I'm puzzled about that as well.
