We have just opened the first wicket and our daughter (4) had a blast. When installing the audio file the night before, there were no problems. I have no idea why it apparently did not work here for some. I have already had the TipToi Manager on the computer, the Advent calendar lined up and in less than a minute was the file on the pin. The current price of around 13 euros is a real snapper. Alone in the first wicket a Menger was told and the memory game was already played. From my full credit and we are all looking forward to the next days.
