I hav a problem with my cs 1.6?

Try not downloading the map from the internet. Rather, download it directly from the server if possible. If not, then download the map and ensure that you're saving it in the proper location. Then figure out where awp_power.wad is supposed to go. .wad tells me that it probably won't be in the maps folder, but I myself am not too sure where it's supposed to go. Maybe in a game-data type folder?
