powerpoint background

[fip04]

hi,
while designing a powerpoint presentation, i selected a design template (named Expedition) and applied it to all my slides. but later i came to know that the presentation had to be made without using any background or design template. so, when i tried to undo applying the design template, i found that the undo feature was disabled.
how is it possible to undo applying a design template to all the slides in a powerpoint presentation ?
thanks in advance

undo will only work while things are still in memory and in some cases only if it has not been saved.

Sounds like you might need to redo the whole thing.
