Thanks for clarifying Gordo. Here's what I did. Clean Install of MVP 2005. Extracted MVP15 total conversion. Deleted all files in data/database folder - there were 23, no 19 which struck me as odd. Extracted roster update into Database folder. Result: If I place an exhibition, the rosters are correct and updated. However If I try and manage rosters at the main menu or start a new season, the game crashes now.
