Access Violation 0x00000000 when loading Pro Tools 10.3.9 HD | Native

[amdini]

I have PT 11, which works perfectly fine, and PT 10 that I use for older client sessions while I transition everything into 11. After installing the latest 11 update, 10 freezes with error during plugin scan.

See attached screen shot for exact error message. It occurs whenever I attempt to load version 10.3.9 of PT. After clicking "OK" on the error pop-up, Pro Tools hangs indefinitely and must be closed manually using Ctr-Alt-Del and ending the process.

Here is what I've tried already:
-removed ALL AAX 32 and 64 bit plugins from the PT 10 directory, and left only the RTAS plugs. Still no load.
-made sure all plugins are up-to-date
-gave admin access to PT 10 during setup and launch
-did clean uninstall of PT10 before installing upgrade
-performed all Win 7 optimizations
-disconnected all USB peripherals
-disconnected Ethernet cable
-tried running PT10 in compatibility mode Win XP SP3
-ran some kind of command prompt "fix" I found on a forum thread related to this issue, where all entities are given "OptIn" to some parameter. Wish I could remember exactly what or where I found it, but whatever it was it said "operation successful"; however this didn't fix the issue I'm having at all.


On the screen shot, you will see the error pop-up during the Absynth scan; however, if I remove Absynth from plugin directory, the error simply appears on the next plugin. Even the Avid AiR plugins cause this error to happen. I went through just about every plugin I have, one by one, and PT still hangs during the scan on all but Xpand.

I can only get Pro Tools 10 to load when removing ALL other plugins from the RTAS and AAX directories.

-All my plugs are up to date.
-I have PT HD|Native v11.1.3 and v10.3.9
-My OS is Win 7 Ultimate 64-bit SP-1
