Sim Or Fyre... Tech Question

[Zips]

[00:44:10] [Disgustipated] [00:45:05] -NickServ- Your hostmask is not valid for account Disgustipated.
[00:44:12] [Disgustipated] ;_;
[00:44:51] [Disgustipated] What do I have to do to become myself again?
[00:45:34] [@[Zips]] auth as you do normally
[00:45:48] [@[Zips]] or register again
[00:45:54] [Disgustipated] Alright
[00:46:38] [Disgustipated] NickServ- Account Disgustipated is already registered.
[00:47:45] [@[Zips]] i'll have to ask the network owner about it... this happened to me before and it's a bit of a pain to get through

So what's the solution. This happened after he updated his mIRC version.

He cannot login to his account because his hostmask changed

-NickServ- /msg NickServ ALLOWAUTH <nick> [account]
-
-NickServ- Allows the specified nick to auth to the specified account. Allowauth does NOT add the hostmask of that nick to the specified account.
-
-NickServ- If no account is given, it will cancel the allowauth for the user (assuming the user has an allowauth).

Allowauth him and have him update his hostmask :)

So, what's the fix for this? Seeing as how I'm just an op, and that may be the problem.
[15:09:27] -> *nickserv* allowauth Disgustipated
[15:09:28] -NickServ- You must have security override (helping mode) on to use this command.

Aren't you a helper? Try doing !god, then executing the command. Don't forget to !god down when done.
