On the 31st of March, 2012, Bungie completed it's data migration of all things Halo to Microsoft servers. Unfortunately they turned off the live Halo stats feed that this app used to pull its data from.
Hopefully Microsoft take over eventually and start providing a similar data feed so I can turn this back on come Halo 4. Until then, thanks for supporting Reach4urPhone.com and HaloGamerFinder.com
