If Colen's suggestion doesn't work, try re-installing the product. This time, run the INSTALLER with Administrator privileges, using the same method Colen outlined. Once you install AB with Adminsitrator privileges, then try launching it as Administrator, too.
If running as Adminsitrator solves the problem, you can configure AB to always launch with Adminsitrator privileges. Right-click on the shortcut used to launch AB and select Properties from the menu. On the Compatibility tab, check the "Run as Administrator" box, then save the change.
