Fixed!
New build here:
TeamRater 1.2.2.
If your league is selected from the list, the program creates the devTracker2_baselines folder, then writes things to it. That folder wasn't getting created when you browse for your league. It does now.
Thanks for finding that one, guys, and sorry for the trouble!
