Quick Question

I just got NBA Live 2008 and the first thing I did was search for a roster update which brought me here. I installed the update but it made absolutely no difference, there are no changes yet all the files are in the sgsm folder. Any Ideas?

You need to load the rosters from the Load/Save menu. Note that it will not affect a Dynasty game in progress, but you can start a new Dynasty game with the updated rosters so long as you select "No" for the 2007 Draft option.
