Tony,

There is a tempo map button in RB. I believe it looks like a metronome on the tool bar. Click that and see if all of the tempos are listed in there? The INS button there will insert a new tempo. You can also change the existing tempos which are listed there as well.

If it isn't shown in the tool bar, click the little arrows to the right (toolbar) to see what is hidden.

If that also fails, hit the help button at the top and search for tempo.
