I am trying for themes given in the beamer theme matrix but when I am changing the theme of my presentation like
CambridgeUs it was changing accordingly but when I was trying with the
whale or any of the theme given in top row of that matrix it was coming with the error as follow:
! LaTeX Error: File `beamerthemebeetle.sty' not found.
Type X to quit or to proceed, or enter new name. (Default extension: sty)
Enter file name:
Can anyone tell me where can be the problem ?
