proshow stopped making dvds

I made two, and now proshow wont make them, nor wil the cmp that made
them play them. Is this a problem with proshow or me?

I am sure this is obvious, but i'm confused
the EX file should work, thanks to colin for his help.

however, i really would like to make a dvd. I used a +RW; is that the
problem? Proshow spent a few hours making these and then when i tried
to play them on the comp that made them, proshow said it was not a
compatible disc or somethng to that affect. when i opened the disc it
was blank, nothing was on it. is this a comp issue or a proshow
issue?

my comp is new, just got in a few weeks ago, hight powered, dual core,
all that, so i hope its not the problem.
