Direct X 8.0 didn’t do the trick unfortunately. Maybe the problem is that I need an older version of Direct X that they recommend? The Exact Error says this:
“DDERR_NOEXCLUSIVEMODE
at: dx.cpp line 183”
The Direct Draw Error window also says that I may need to use the SETUP.EXE from the Diablo CD, but I did not use an ISO to install the game, so I do not have access to this file.
