Alright, here's the situation. I tried to download the files from the site, and was successful. I then tried up launch a new OD using those files, but they aren't recognized by the Xbox. They're just excel files. I think we need the OD file downloaded from the console, if anyone can get to that.
I was able to launch an OD using a Ladder file that was saved to my Xbox's hard drive, but that one was apparently saved in Week 6 of our first season. That must be the last time I saved a copy of the file.
Unless somebody can download the current file from the game on their console, I believe The Ladder is dead...
