Admin pass not working

[Hellspell]

i play assaultcube on a different computer to the one i run the server and have all my maps and modified files and gui stuff on because i can no longer play on that computer. I haven't been bothered enough to move that stuff as of yet to the other computer. This is why it would be more convient to type the setadmin command, i did know the giveadmin command but running from room to room is tiring. I'll get round to moving my server files and maps and all the other stuff eventually. What is the command to take admin back of someone who i've given it to?
