Hopefully some one here can help as EA has been of no use. I've installed Sims 2 on my PC, specs are

P4 2.66
i865 chipset
160GB Seagate hdd
Mitsumi 48x CD-ROM
HP DVD+R/W 300i
1.5GB RAM
ATI Radeon 9500 Pro (Catalyst 4.10 drivers)
Windows XP SP2
Sound Blaster Live! Value
Netgear USB 802.11g NIC

When trying to launch the game, I get the splash screen then it crashes with a generic error. I've tried disabling everything at start up, have tried several video driver versions, have uninstalled the game including manually removing every part of it from the drive and the registry and still get the same error. Any thoughts? I thought maybe it was an issue with SP2 but it runs fine with SP2 on a friends PC.

Thanks in advance for your help!
