You've got me confused.. first, what version are you using?

v1.5 comes with Admin Profiles already installed (now referred to in the menu as Admin Access Management).

In previous versions, you needed to install the "Admin Profiles" mod, which then appeared under Tools->Admin Profiles. It sounds like (I might be misunderstanding) you installed 1.5, then tried to install Admin Profiles mod (on top of the already existing code), then tried to uninstall it? If that's the case, my advice would be to start over with a fresh install - or use a compare program to find out what has changed, and revert it back to stock 1.5 code.

If i am misunderstanding, please clarify..
