Etherica map breaks game

[honrguard]

I downloaded the "Etherica" SP map and it seems to have permanently ruined the game. The texture for the Nanosuit is gone (the character model is white), aiming is darn near impossible since the animations were changed and the gun's constantly swaying around, the TOD was changed making the HDR blinding, and so on. I deleted all the folders that were added, but that didn't work since I think the map replaced the regular files as well. Re-installing didn't work either. Is there any way for me to re-obtain the regular files?

EDIT: I deleted the folders that the map added/changed and everything was restored except the Nanosuit texture. Also, the folders I deleted are still gone, though the game works as if they were still there. The game is playable now, but I'm not satisfied as it's not exactly as it was before. I really need to find a way to get ALL of the original files.

Just delete everything but your saves, and other custom maps you want from the Crysis directory. Then launch Steam and verify game cache. It should re-download it automatically, but if not verify :)

I deleted all the files, but re-installed the game instead. Everything's fine now. :)
