Hello brothers! I have a bit of a problem. I used to play Dawn of War on the old cd version and decided to get Soulstorm in preparation to getting the main DoW (I’m contacting sega about it as I learned I can get a key to swap over). However in playing Soulstorm, I noticed I couldn’t use everything I was used to. I could not build turrets (they wouldn’t even show up in my servitor’s build screen), and couldn’t upgrade my stronghold due to it not showing up. Is there something wrong with the files or am I doing something wrong?

UPDATE: After receiving the key for the base game and installing it, it works as intended. Thank you to everyone who helped!
