nah, it isn't about re-installing the game as a lot of us have put in a bit of time getting rosters up-to-date and it is quite annoying to re-install....it's not the game that is the problem I'd say, it's the roster....
here's my error messages that I get when I try to sim the first day of the season....

both of these error messages come up and game shuts down....
I tried to replace the original & working dbf files as mentioned, but it did not help as dynasty still crashed....
any help would be appreciated....
cheers

EDIT: I think it's due to me editing dbf with Excel. I figured it would be alright considering it was safe in Live '05. I guess not
EDIT #2: Re-did dbf-editing but with downloaded DBCommander, and have not had any dynasty crashes yet
