Go here:
www.talksoxbbl.com/downloads/talksox.lg.exe
This is a self-extracting file I created for you guys. Should be ridiculously easy. Just click on the talksox.lg.exe and make sure you choose your default OOTP5 directory. For example, on my computer it is: C:\Program Files\Out of the Park Developments\OOTP5
Then load your game, click file, then open, and choose talksox.lg. Congrats, you are now in our league.
If you want the ballpark pictures, go here: http://www.talksoxbbl.com/downloads/.../ballparks.rar
Download these files in the directory ootp5/graphics/
This is not mandatory, but is pleasing aesthetically.
If you want player photos, this is a big download, about 8 megs. You have to manually change the player names. Once again, pleasing, but not in any way necessary. The link is http://www.talksoxbbl/com/downloads/...2007photos.rar
