Visual studio can't find included elements properly

I was making loading screen for my game. I found that guide: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

I made everything like in the guide, but VS don’t see elements of MoviepPayer.h even if i have included it with entier pass. (I have MoviePlayer in game’s build file). I didn’t included Specification of GameInstance class in DefaultGame.ini but i made it in UE4 editor in projects settings. And the funny moment that it’s compiles perrfectly well with those porblems and UE4 even exported it into normal game (exe file) and it works.

It asks for ‘;’ in 20 string that for me is odd.
21 and 25 - id not defined
22 - name with ‘:’ after it must define class or namespace

I wan’t to deal with that, of course it compiles even with that problems, but working with loadins screen and MoviePlayer in future will be much esier if i underrstand whe these problems here and how to solve them.
