PT 11.2.1 Access Violation

I did a clean uninstall of PT prior to installing 11.2.1 on my Windows 7 64 bit system. Upon trying to open PT 11.2.1, while scanning my plug-ins I get the following;



"Access violation occurred Thread cause a DEP Violation at: 0x000000000055D8FBE0"



Anyone have any idea what is causing this?
