MelloTrainer Admin error


Hey just new to the whole modding community was hoping to get help with the Mello Trainer.
I fallowed the instructions to post the Hex number to whitelist myself into the Mello Trainer but I am having an error telling me I am not an admin. So I must be doing something wrong. Can someone tell me how I am to put it in or what it should look like after I have edited the admin adding section of the MelloTrainer config file?
