I have completely uninstalled and reinstalled both VC++ 2008 Express and DarkGDK (a few times now) and have narrowed the problem down to the 7.4a update.
If I run the default code in the Dark GDK 3D Game wizard prior to installing the 7.4a update everything works fine. After the update, which overwrites the header files and libraries in the DarkGDK folder, no 3D objects are visible.
Ideas anyone? I've searched and found an old thread with a similar issue, but it didn't have an answer. I thought maybe a new thread on the subject with a more specific title would help.
[edit]
More information.
I installed the main download of DarkGDK dated Nov 16, 2007, then installed the update from Nov, 2008. Everything works fine up to that point. If I install the 7.4a update from Aug, 2009 then I can no longer see 3D objects.
