The original package of Admin Tools Core 2.0.1 was broken. Please re-download.
We regret to inform you that the original Admin Tools Core package was missing some files. This made it impossible to be used in clean installations, i.e. if no prior version of Admin Tools existed on the user's site. Users upgrading from Admin Tools Core 2.0 were not affected. Likewise, users of the Admin Tools Professional release were not affected.
If you had downloaded your Admin Tools Core package before March 14th, 2011 20:30 GMT please re-download it to ensure its correct operation.
We apologize for the inconvenience.
