DoraAreGames: I asked for help for this several days ago on the official forums for the game but never got a response so I thought I'd try here. It's the GOG version, and I tried installing the fix the developers have for this apparently widespread (but frustratingly illusive) issue that happens in random locations for players, but haven't had any luck. Here's what's happening:

Shortly after Wilbur is launched in the rocket by his Granddad in the first chapter, the game crashes and throws up the exception error on trying to load the next scene...
"An exception has occurred!
ORGE EXCEPTION(3:RenderingAPIException): Failed to DrawPrimitive : Invalid call in D3D9RenderSystem::_render at ..\..\..\..\..\RenderSystem\Direct3D9\src\OgreD3D9RenderSystem.cpp(line 3116)"

I downloaded the fix and followed the installation instructions, but unfortunately that doesn't seem to have resolved anything. Any suggestions?
