Engine has a small bug, it doesn't set meta result in GameInit, but it is nothing critical.
Your problem is that you want to load superheromodvault.amx which doesn't exist or AMXX can't open the file. Make sure your superheromodvault.amx is in the plugins directory or remove it from plugins.ini
stats.amx also cannot be loaded because you don't have the CSStats module... you can a) enable it b) remove stats.amx c) ignore it, nothing serios will happen, you will only get the error everytime you start
I think logs didnt change in CZ so run the .exe with
parameter and post your AMXX logs (in moddir/addons/amxx/logs/[latest file]) and HL logs (in moddir/logs/[latest file]). You can also try to find an eror message in them ;]
