I have just installed this mod with no problems. Everything loaded fine.
Went to admin - no hint of the mod except under customers menu.
I select and get this message:
"Sorry, your security clearance does not allow you to access this resource.
Please contact your site administrator if you believe this to be incorrect.
Sorry for any inconvenience."

Then it suddenly occurred to me.
Admin profiles mod is installed.
Even though I was logged in as the main admin I still had to give myself permission to use the mod!

Just thought others might like to know.
