Enhanced Protected Mode (EPM)

I am running Windows 7 64 Bit with IE 9.  when i try to open an Adobe document I get an error that Adobe Acrobat does not support Internet Explorer's Enhanced Protected Mode (EPM).  Either install the latest version of Adobe reader or disable EPM in Internet Explorer.

I have done both and still can not open a web PDF!!!!
