Visual Studio (.sln) ERRORS

[Nick4411]

(BEFORE ANYTHING, MY SOURCE IS : Gunz 1.5 Repack by Jur13n #1 (Edited) )))
_________________________________________________________________
Ok so I am kinda newgen with sources, that's why im here to complain.
The reason I am here is because I tried to add commands(thats not the problem)
then I thought I just had to restart the MatchServer then it would update in the Launcher.
But nope, it does no update at all.
Then I get information from someone saying I have to build Gunz.sln and matchserver.sln , and when I try gunz.sln I get like 75 errors.
I really don't know what the problem is, someone PLEASE HELP i am begging, thanks
