Warzone 2100 won't start

[L4W]

Hello, I downloaded Warzone 2100 today. I installed it, and at start I was setting up the options I would like to have. When I was in textures, I changed it from 256 to 512 and restarted. After it, when I start Warzone 2100, it won't start! I tried to uninstall it 2 times, even uninstalled OpenAL, I searched for registry of that game and nothing, it doesn't load still. Can anyone tell me how do I make it back to defaults or something? I cannot do it from game because it keeps freezing!

Thank you for help
It looks like the game freezes only when I change the texture resolution to 512, but there's not much of a difference!
