Map problem

[Dyingsoul]

I am searching for space themed maps, but when i am trying to load, there is a HDR error message. Since the .bsp file is protected, i cannot add HDR to the map with hammer....

I am searching for some cool space and spaceship themed maps, if anyone has it, working with SFM please tell me... If you are one, who can create maps for me, then tell me and I will share the credits with you on my new Alien themed project.
