Here is the transcript from the "chat" I had with MS tech support. He could be blowing smoke up my ass... who knows.

{Richard}Welcome to the Xbox North America Customer Support! My name is Richard!
{Me}Hi Richard
{Me}Did you see my question?
{Richard}not yet mike, could you kindly restate it again?
{Me}The XBL scores were reset. Is it a temporary "glitch" or is it permanent?
{Richard}possibly, because the XBL scores should be continuos.
{Me}I'm not against them being reset, but you guys have to notify us. And after only 5 weeks on the market? Are scores going to get reset every 5 weeks?
{Richard}i do believe so.
{Me}I've been an XBL subscriber since beta testing in 2001. This is a poor decision by Microsoft and I'll be cancelling my subscription if this is the case.
{Richard}im sorry. i believe that they are already fixing the problem right now and please do expect for your scores to be updated tomorrow.
{Me}Good news! Thank You
{Richard}and please do be rest assured that we will fix this problem permanently so that you wouldn't have any inconvenience regarding your XBL.
{Me}Just notify the community if you want to reset the scores. Once a year would be sufficient.
{Richard}we surely will, actually, ive already filed a report regarding your issue.
{Me}have a good day.
