Problems with loading pro evolution soccer five on pc

i've just installed pro evolution soccer 5 for my son's christmas present and
no problems with the actual installation. my graphics card (gforce fx5600)
is compatible; we've installed directx9 and have got the latest driver for
the card direct from nvidias site. yet when i click on the icon on the
desktop i get a small hourglass symbol for about a second and then nothing.
if i go to my computer and click on the pro evo icon and select autorun i get
the pro evo list of options and select play and then get the same hour glass
symbol and nothing again.
i got my other son star wars battlefront 11 for the pc at the same time and
this runs with no problems at all. any ideas? thanks, Jim
