check your plugins folder and make sure superheromodvault.amxx is in there and is spelled correctly...
also check to make sure you have the cstrike and engine modules enabled in your modules.ini
KsqueaKJ: you should not have both superheromodvault.amxx and superheromodmysql.amxx in your plugins.ini one should be disabled or removed and since I assume you are not using MySQL saving remove superheromodmysql.amxx....
