Spawn Actor/Object from code

As I cannot create a topic, I will answer here hoping that someone might give it a read.

Spawning a Blueprint in c++ with 4.7 error C2027: use of undefined type ‘UBlueprint’

Just trying to spawn a Blueprint Projectile instead of the c++ class projectile within the Twin Stick Shooter Template.

Read through all the other topics and tried to do it like it has been described here: Spawn Actor/Object from code - C++ - Unreal Engine Forums

Sadly, I just cannot seem to get it to work, even after many hours of trying out different things. Given that I am very new to c++ and used to Java, I might be lacking the proper skills, but I still would love to know where I made a mistake in this simple process. here is a screenshot of the errorlog and code: Dropbox - Error

Any help would be greatly appreciated as I just cannot get around the Ublueprint error.

Thanks so much!
