ASSMod isn't saving admins.

Sorry for wasting your time, but I really need some help from whoever I can get it from. I’m running a GMod dedicated server from srcds (Windows). It’s working great. People join, blah blah blah. I’ve just installed ASSMod and am LOVING IT! The only problem is that every time I change the map or restart the server, I have to enter the console commands for making myself a server owner. Plus, if I restart the server and don’t join, I can’t make any of my admins… admins.
Yeah, I’ve tried adding ass_rankings.txt to the data folder, then adding my name and unique Steam ID (found on this page of the ASSMod thread: http://www.facepunch.com/showthread.php?p=15515657&highlight=admins+-saving#post15515657)

By the way, is the default picture for Facepunch forums a dog’s bum with sunglasses on the tail?

Yes.
