O.K. it doesnt' sound like your tama has anythign wrong with it. You can't go to school even if you are a todler until you get your letter in the mail, and as for the buttons, I've noticed that the buttons on some v4s are slightly non responsive, but hardly at all.
And I can't really tell if you meant getting on the internet and loging on tamatown or going to the connection icon and selecting "work" when you said "tama town preschool".
So if I were you I would just give it like a day or two, and see if things work out. Then try writing a hate letter.
hope this helps.
