My gears of war3 experience,
i waited in line at midnight on monday to get my copy, the first night i got it home i tiped over my xbox 360 with the disc inside it (a bit of gears and beers completely my own falut.) and scratched the disc so badly i had to buy a second copy.
Days later my account was magically 'reset' and all my progress lost upon loading the game (collectables, chapter completion, etc, I did however maintain my level and ribbons...suprisingly!) and i still cant figure out why or how that happen. So i started over on collectibles, a day later i could no longer play any game mode split screen because my wifes profile had become 'courpted' and when her gamertag was loaded the game ALWAYS locked up.
Later my gamertag began to lockup gears of war3 and i could only use a new or no gamertag to load the gears of war3 software.
For whatever reason i cannot play gears of war3 on my current profile, it locks up and i have to hit the power button.
If i use any other gamertag the game works perfectly fine.
I have tryed virtually everything, the end result is, i have formated my xbox hard drive, recovered my gamertag (profile), and attempted to play the gears3 disc with nothing other than my gametag loaded on the hard drive and still it will not work. (no gamertag or OTHER gamer tags work fine.) So as soon as i load a diffrent gametag it works fine, any insight would be helpful. the epic forums is rampant with this topic and there is no support/or acknowledgement shown.
Major Kilowatt brought it to my attention that a temporary fix is to load the game with no profile, and than load yours. I load campaign with no profile and than guide in with my profile, this brings me back to the main menu and lets me play for a bit, but it locks up after there is an act/level change. Also my profile spits out ./0123456789 on the far right hand sidee from time to time. keep in mind i have literally nothing on my hard drive,s o if my profile is courpt its on epics server and has nothing to do with my hard drive. If you have any insight or feature a similar issue please let me know. I have an open ticket with support, and they have esclated the issue to windows development, but i have 3 to 5 days to wait for a reply.
