lost administrator status

[rekt5782]

i've upgraded and done a fair amount of stuff on my emac recently, so don't know exactly what may have caused this. but i no longer have administrator access on my computer.

but the two things that do stand out in my mind are that i've upgraded to 10.4.4, and ran disk warrior immediatly afterwards. i have always only had one account on this computer and its always been an administrator. now i can't seem to fix the problem because i no longer have administrator access.

any ideas on how to get my permissions back?

thanks.
