Hi DjNDB, thanks for your effort!
Attached the dxdiag.txt, (zip file) and tried to re-install (un-install first with delete save games), with a new fresh downloaded setup file, (cleaned the browser cache).
Have even tried to clear out registery references to ToMI, which resulted in being able to register again through the splash screen, (this is only possible if I disable wireless, otherwise)
Did the steps with msconfig, and did a minimal boot, but no luck... (have tried it before, though).
Think I have tried all suggestions in the forum (including the props file from Will)
Kind regards Peter
