I already ran ManuAdmin Mod and GSManager on my pc and both ran perfectly.
Yesterday I tried to run GSM on VPS, everything was ok but when I tested that server, commands were not working. Also I didn't saw any welcome messages 
However, scheduled messages were working fine.
Log files doesn't show anything wrong.
I tried old Manu Admin Mod and it worked fine 
VPS is running Windows Server 2008 x64, I only installed Visual C runtimes.
Is there any other runtime that I should install?
**************EDIT***************
I restarted VPS, and now I see welcome messages as well. When I try something like "!fakecommand" it reports that command is not recognized, when I try a read command like "!use token" GSM restarts
Here is log :
