Hi!


Follow the path to install the map correctly, like this   

:cstrike/materials/skybox/     <----- here is your texture for the sky if you don't put the .vmt .vtf files in to your server the map will not work

:cstrike/map/   <----- here is your map (gg_Elite_Crossover_Final)


make shure that in your server.cfg this is 1   

sv_consistency 1
sv_allowupload 1
sv_allowdownload 1
sv_downloadurl "http://www.mydomain.cz/cstrike/"  <---- point at your fast download
