There isn't a direct way to do this, but you can do it by creating a new tournament, setting the League and Season of the tournament (you don't need to set *anything* else at all for the tournament), saving it, copying it to the 2nd PC, then opening the tournament in the TD on that PC. The TD will notice the League and Season aren't in its database and ask if you want to import them. Repeat for all leagues & seasons.
