When I start up one of the official campaigns, the intro movie does not display on screen. The sound plays, so the narrator speaks, sound effects go off, but the video does not display, leaving me looking at a loading screen while the sound plays.
I am running a 2.3 GHz AMD V140 with 2 GB RAM, Win 7 64-bit, an ATI Mobility Radeon HD 4250 and Catalyst version 2010.0617.855.14122. This machine just has basic NWN Gold installed, but I have another machine with HotU installed and updated to 1.69 and I have the same problem. The second machine has Win7 32 installed, a slightly faster single-core Intel processor, a little over 1 GB of RAM, and an ATI Card (dunno specific model or Catalyst version off the top of my head).
