Could I get some information about saving game data?

So far, I’m getting a compile error in my header file claiming that FArchive is an unrecognized type. This is happening despite having the following in my header’s include statements:

#include "Serialization/ArchiveBase.h"

Did I get the include statement wrong? FTR, this is in 4.6.1. It’s a bummer because I’m trying to see if I can eventually use Rama’s save system to implement a full-scale quick save system that uses the UPROPERTY macro’s SaveGame keyword to serialize game data.
