I just created a slideshow and it doesn't play correctly

I just created a slideshow on one windows 2000 system. I have spent in
excess of 25 hours editing the show adding music, text to slides etc.
Version is 5.02.

I want to distribute it to others on my trip but when I try the .exe on
another computer I get no sound and it seems as if the slides hang (or
are very slow). Any ideas. I just paid for this product and am really
miffed!!!

Help!!
