First try to connect with xbox live, if its still possible then your console is good, just create a new live account.
Otherwise you have to buy a new 360, i got the arcade when i was banned and i just used my old harddrive and live account to play again.
This is the risk you take with playing copies on live
I wouldn't buy another 360 and support M$. And modding and copies are still worth it despite that...
QUOTE(quepaso @ Oct 22 2009, 11:23 PM) Nintendos online setup, WFC, is basically 2 cups and some string compared to PSN and XBL. I doubt they even have the manpower to even investigate everything that happens on nintendos network since they live by a mantra of less employees doing more for the company. MS and Sony have teams of people monitoring their networks all the time. Its why nintendo is a joke when it comes to online.
