Ah, the problem is that the steam id from file is not the same as the one retrieved by plugin, so at this check it fail:
PHP Code:
if(equal(PlayerAuthId, WeapData[WeaponIdentifier]))
Can you write
status and check your steamid if it's the same as the one from file ?
Be sure it's not detected as STEAM_ID_LAN or something.
I have edited the post above, compile the new source. It will generate one more log: "Detected steamid:"
Check if the value is the same as the one from file.
