Problem with Rugby 2004

Ok so today I bought myself EA Sports Rugby 2004, a game which I have been wanting to get for a while now. On the back, it had the system requirements to play the game, and while I'm not much of a pc expert, it looked like I could play the game. But when everything is installed, the game won't run. So I checked the manual cd that came with it, to see if there were any clues there. None. Then I opened up the 'EAsy' sytem information window, to find figures which look a little different to the ones typed on the back of the box, and in the manual cd. So what do I do?
If this helps, I've tried to use the Program Compatability Wizard, to no avail.
Heres a pic of my 'predicament'

Thanks in advance

It probably need 64mb of ram for Windows 98 or other systems, It probably requires 128mb for XP. That's my guess at it.
