Hi, I have the exact same problem except when mine is loading up from the start, all I get is a black screen and then it eventually closes down to desktop.
I wrote to the technical support guys - see reply below.
OK here's what you do
1. Uninstall NWO
2. check motherboard for VIA chipset. If present please update to V4.45

3. Install DX 8.2 (on disk) (e=cd rom drive E:\Dx\DirectX filename dxsetup.exe)
4. reboot computer
5. Download and install latest drivers for your Grapics card
6. same goes for the sound card.
7. Install NWO
8. Install NWOUpgrade1.0-1.34.exe (attached to this mail)
I've done all this and it still wont run ok. Im using an ATI 8500 craphics card with updated drivers, along with windows 98.
Anyone got the answer ??
cheers
