WE have been using EY TT since last year. We bought FizzBook spins as recommened by the guy who came and did the TT training. They have been the bane of our lives because they have no disc drive and to install anything new it has to be transferred onto a USB device and then onto the FizzBook. Except it won't!!!! We still haven't successfully updated to the new version. Please help - in words of one syllable.
