Unfortunately there were some bad settings in the roster set that was released with the first patch. We have fixed these and the new ML quickstart is now available. To install, you have two choices:
Through the Add-Ons Center
1) Open OOTP, then continue the current game
2) Go to the Game menu, and select "Add-Ons Center"
3) Click "Reload Add-Ons List"
4) A new one called "Updated major league roster set" appears, click on "Download", and after the download on "Install"
Manually
1) Download the following zip file:
www.ootpdevfiles.com/ootp/rosters/majors.zip
2) Unzip the file to the major league quickstart folder, for example "My Documents\Out of the Park Developments\OOTP Baseball 9\quickstart_games\Majors.quick"
That's it, now when you start a new 2008 ML game the new rosters are being used.
Enjoy!
