They recently released a new XBLstealth plugin a couple of days ago. You should be just fine when you get that. Reset your console and BOOM! You are fully stealth haha. I love that message when i get online.
Yessssssssssssssss ! It's work now thanks to you all ! How can I be awared if they change again their xex ?
this does sound like a connection error i understand you got it working but it does. next time it happens and if . when you are on the correct xex just clear your cache ive heard this a few times and suggested this and it works.
