Admin Password no longer works

[SwiftLives]

So, I go to log into my account this morning on my iMac, and it tells me my password isn't valid.

Unfortunately, my login is the admin account.

At the moment, I have no access to my files, and cannot do anything that involves admin privleges, such as repairing permissions, etc.

Oh, and I can't find my iMac instasllation disc. Or my Tiger disc.

I'm pretty much boned until I do find them.

Once I do find them, will I be able to reset my admin password without a valid admin password?

My suspicion is that something got corrupted somewhere - possibly permissions. Anyone run into this before?

Also I don't suspect anyone of changing the password, as the only two people with access are me and my wife. And my wife doesn't mess around with system prefs.

Is caps lock on? If it's a laptop check numlock as well.

once you have found your restore cd's or tiger ( or even 10.5 on friday)

you can reset your Admin account from the installer
