Forefront TMG Error Refresh Failed Error 0x800200003

Hello All,
I am getting a unique and strange error message. I had Microsoft Forefront TMG 2010 installed on my Windows Vista machine. I previously had IE 7 installed on the same machine. There were no issues with both being on the same machine.
I recently updated to IE 9 and from then, I have been getting an error message.
Is this some compatibility issue? Or do I need to update something on my machine.
