His headstone would be lovely....

I only got this game last month myself. Barring some technical difficulties, I'm just blown away by it. It's so much more than a sandbox. The fact I could go in and make a map to play on or experiment with all sorts of things with these games make it more like a toy box and I swear, I feel like a kid playing around with this. And I rarely get that feeling with contemporary AAA games. 
I'm feeling it. I don't know what I'm doing half the time but I'm feeling it. 
Though I have to admit this whole thing is terrifying at first. I don't think I've ever felt my heart really sink in any game, but seeing a whole squad get obliterated while inside their Stryker definitely did me in more than once...
I'd also want to say thanks to whoever is responsible for having regional pricing on these titles. I live in a third world country so getting games  is pretty rough on me, but when I saw these games on sale I immediately bought everything up. SF2 first, then the very moment Black Sea came out I got it as well.

I see. I appreciate the input.

Do these crashes occur regardless of which side you are playing ? It seems strange that during the plotting of a fire mission is when you get the crash. I'm not specifically aware if a sound is associated with any of that process (other than the radio chatter for the fire missions - afterwards). Until this point all of the sounds play fine within the game as far as you're aware ?
Is your extracted folder for the HQS 3.3 mod located within the 'Z' folder that is within the 'Data' folder of the game ? Or is it located within the User Data/Mods folder (within the Documents folder of your user account) ? If it is located in the latter location, you may want to create a 'Z' folder within the game directory's 'Data' folder (if you haven't created one already) and put the mod there. So in the case of CMSF2 from Steam the location would be (that appears to be on your D:):
D:\Steam Library\steamapps\common\Combat Mission Shock Force 2\Data\Z\HQS 3.3   (or you may have it in the 'HQS CMSF CMSF2 CMBS CMA\HQS 3.3' directory).
The main game folder location shouldn't really be an issue as far as I'm aware and it shouldn't be necessary to move the game around. As long as it is located on a drive that is always present (preferably not an external drive that may get disconnected).
I guess the really strange thing here is that the game continues to crash after the mod has been removed. The game has been completely exited before the mod is removed, correct ? By removing these mods you have either deleted them or moved them completely out of any game directories, correct ? I wouldn't imagine that Steam would somehow be caching any of these files so that they somehow remain present even after they've been deleted/removed.
You can play the mod sound files without problem outside of the game, correct ? Do you know what sound chip/card you have in your computer and what driver it may be using ? I don't know of any specific audio chips/cards that would be incapable of playing these sounds within the game. Looking at one of the wav files,  'American adjust fire out 0' it has a 44100Hz sample rate, 32-bit (float), Mono. I don't know if editing/resampling these files to be 16-bit or 24-bit PCM might help or not. I'm not sure of the exact data on the original files, so such editing/resampling may make no difference.
