I too have problems with SS2008
I think I have tried everything suggested on the forum, but can't get the game to work.
(Everything is updated on the PC...)
I've downloaded the setup-files (game, updates and add-ons) yesterday from the webpage, therefore I don't think I have to use the update-files, because the ShipSim2008.Setup.exe is already V1.4.2.
Here is the process I've tried:
1. Installed ShipSim2008.Setup.exe
2. Started game - shows version 1.4.2
3. Installed ShipSim2008NewHorizon.exe
4. Started game - shows version 1.4.2
5. Installed ShipSim2008.Elbe.exe
6. Started game - shows version 1.4.2
7. I didn't try any mission but quit the game, then the error "Questviewer has found a problem..." appears.
8. I unregistered and uninstalled the game, deleted the mentioned folders,
restarted the PC,
reinstalled only the ShipSim2008.Setup.exe-file,
started the game (this time the VSTEP-video shows up, it didn't do that on the previous install today),
I pressed "Esc" or "Enter" to skip the video, the PC exits immediately to Windows with the error "Questviewer has found a problem..."
I'm looking forward to any help or suggestions
