I think it might have something to do with the fact that LSAC's policy regarding PDF downloads has changed so till JY and Alan figure that out, they have frozen purchases in your best interests... just a theory.. not sure but seems plausible.
Alan—unfortunately I'm still having the same problem (just had it when looking at the "Gaining back confidence" thread). I checked the App Store and didn't see an update—did you mean it's forthcoming from there?
