After having tried a few things, including installing ioRTCW (https://github.com/iortcw/iortcw; it's a nice touch but does the same thing in my case), I have finally found the solution: you have to wait a few minutes, staring at the grey screen and some time later MP will start and work fine.
I wonder, what it is trying to do in those minutes? Maybe it tries to "phone home" but the local network is strictly local, so it gives up after some time.
Anyway, the original question was the opposite, SP not starting and my rumblings here won't help with that.

Also, if I manually edit the wolfconfig_mp.cfg file and change r_mode to a different value, then the screen resolution obviously changes. So I can see the grey screen in high resolution now 😀
Event Viewer shows WolfMP.exe crashing but there is no useful information there.
This means that video is working well but then what can be the problem?

I have the same problem on two XP systems except that SP runs fine but MP does not start, only the above grey screen. Tried "safe mode", too.
One is a P4 with an ATI 9200, the other is a Sempron with a GeForce 5200. Both are connected to a local network.
No log info is to be found. Any ideas?
