Here's my info:
purchased an Xbox in November of '03 and began using LIVE immediately
spring (summer?) of '04 I installed an Xecuter Lite chip and all the popular apps and emulators
replaced the HD with a small 30 gig a few weeks later, transferring all the data from original HD
I've always used LIVE w/ the chip off of course (the bios prevent accidents automatically)
I did try out the French PAL version a month ago, and I also forgot to delete any of these files
purchased Halo 2 on Nov. 9th and played several hours on live
played several hours on live on Nov. 10th, signing in and out many times - no problems
played a few rounds this morning (Nov. 11th) before coming to work - still working fine
I feel as though I may have passed "the test", whatever that may be, but I also fear I may be delay-banned at any time.
Not sure what to do. My gut says to stay offline for a while and wait out the storm, but my Halo 2 cravings are beckoning.
According to what MS reps are saying though, your gamertag is not harmed in this ban. You can buy another Xbox and play on, so it looks to be all hardware and/or software related.
