Generating Schedule problem

[bmilito]

Our league is working on transistioning from DMB to OOTP. As a test, I am working on recreating our last season of DMB in OOTP. As part of this test I have done the following:
- Created a new Universe
- Imported the 2007 version of the Lahman database, since this was the season we used in DMB
- Released all players and deleted the 30 MLB teams
- Created the 8 teams in our league

I am on Jan 1, 2007 and am trying to Generate a New Schedule in Commissioner mode. Under "Edit League Schedule, when I hit "generate fictional schedule", I get a "Cannot generate schedule for league with interleague play or with unbalanced schedule. Set 'Interleague Play" to OFF and 'Use Balanced Scheduled Format' to ON in league settings." In my league settings, I have "Use Balanced Scheduled Format" checked, however, I do not see an option for interleague play. I do, however, see an option which says "Scheduled Loaded from File" and it says "major_league_ml_c_2007.lsdl". I'm guessing that this is my issue however I am unsure how to clear it.

My schedule options are as follows:
- Schedule Spring Training: OFF
- Season Start Date: Feb 17, 2008 (Feb 17, 2007 does not work either)
- Force Start on Certain Day: CHECKED
- Auto adjust date: UNCHECKED
- Number of Games: 140
- Schedule Balance/ Use Balanced Schedule Format: CHECKED
- Select Typical Series Length: 3 games
- Schedule Loaded from File: major_league_ml_c_2007.lsdl
- Hold AllStar Game- UNCHECKED
- Disable Playoffs- UNCHECKED
- Use Custom Playoffs- UNCHECKED


I have tried to import other league schedules for 1 division of 8 teams and 140 games, however, it tells me that I cannot import the schedule due to the "Interleague Play" option being selected.

Any help is greatly appreciated.

Thanks!
