Hello tiffycody! ^^
If this is the first time you're running the game, then the game is trying to play a video. If it's crashing here, it might have something to do with the video.
First, could you go into the folder where DMMdRC was installed, and then look for the folder called "dx"? Inside there are all animations and videos for the game.
Find one called "dmrop.ngs", copy it, and paste the copy back right there, in the same spot. You should now have a file called "dmrop - Copy.ngs". Please rename that file to: "dmrop - Copy.mpg". You have to change the file extension.
Once you've renamed the file, try opening it. It should open in Windows Media Player, and if it doesn't play, then you may just need to install a new video codec. ^^ You can get a good set of them here:
CCCP - Combined Community Codec Pack
Feel free to download and install that.
