Errors/Warnings - Kann mir da jemand helfen?

Hallo Community!

Als ich aus dem Showroom ein GM geladen habe und mir alle dazugehörigen Includes zusammengesucht habe, habe ich einmal das GM Compiled.
Mein Problem sind diese Errors/Warnings, anscheinend muss das ein oder andere Include kaputt sein.
Schaut doch mal drüber bitte ...
