Now it works, now it doesn't. Why not?

When I launch the market place content via the binary version of the UnrealEditor, it works just fine…
When I build the market place content for OSX via Xcode, it runs just fine…
When I build the market place content for iOS via XCode I get errors about video streaming apps
but most importantly…

When I launch market place content via the editor I built from source, I get this error:
“The game module ‘ShooterGameLoadingScreen’ could not be found. Please ensure that this module exists and that it is compiled.” (obviously this one is for the shooter demo, but I get the same error for the strategy demo also)

Again, it worked jus fine when I launched it via the binary version of the editor, but not when I launched it from the editor I built it just refuses to start and I have to close the editor down.

Does this mean that all content downloaded from the market place first has to have it’s source code infused with the editor’s source code and the editor then has to be rebuilt to contain the code from the market place content???

…or is this a bug of some sort?

Either way, how do I get to use the market place content from the editor I build. And yes, I did include the contents of the two required zips. So what now?

…and how do I get the shooter game to run on my iPad when it builds and installs without any problems but just fails to run due to missing components?

Please see here: Cannot open ShooterGame on Mac - Platform & Builds - Unreal Engine Forums, although I’m not sure it’ll answer all your questions. If you still have problems after reading it and trying what’s suggested in there, let me know.
