Thanks for playing! You are the first person to leave a video here. I notice that you meet some issuses when playing.
Due to engine limitations, when playing large custom maps in WAW, you need to adjust the texture settings to manual-->high instead of automatic.(You can see the screenshots in my previous reply.)This will solve most of your freeze errors and also useful for other maps.
Btw, I noticed that the map you played is not the latest version, there may be some bugs. You can download it again.(At the same time i updated this map to lower its difficulty)
Finally, for some in-game advice, you can check out the EE tutorial and use mystery box to get more powerful weapons.
