Unfortunately such database issues aren't uncommon in NBA Live 2005's Dynasty Mode but usually you can work around them. There are a few things you can try, but be sure to
make a backup of your Dynasty first, just in case.
- If you're using a roster update, re-load it before loading your Dynasty save.
- If that doesn't work, you can also trying copying the teams.dbf file from the roster save folder to your Dynasty save folder.
- If you started your Dynasty with the default roster, copy the teams.dbf file from the originaldb folder to your Dynasty save folder instead.
- Delete the contents of the workingdb and currentdb folders.
Hopefully, one of these solutions will allow you to progress to the next season.
