Alright, I've been through my phpnuke site @ gamemoviemaking.com and for the life of me I can't figure out why your having such a problem with your admin privileges. The only things I can think of for you to check are:
- make sure you have an administrator usergroup created and that the usergroup is active.
- change values in the nuke_users table to another value between 1 - (however many possible user levels you have onsite). The reason for trying this is maybe your admin level is another number than 2, although I seriously doubt it.
- upgrade phpbb if you haven't already to the current version.

...other than the above, I have no other guesses as to why this isn't working. Simply put, if the db accepts the changes in your nuke_users table, there is no reason phpnuke should not follow suit, at least not a reason I'm aware of.
