Nuendo Hanging at Startup

Help!!
My box was running fine with Nuendo 5.1.1. I then loaded my final plugins, East West Quantum Leap Collosus, and Synphonic Choirs. My box now hangs at Nuendo startup with the following message:

Initializing: scan states

What is that? The only thing I can do it go to Task Manager and kill the process and that does not work most of the time.
I removed the 2 plugins but the problem still happens. I then de-installed Nuendo 5 and re-installed but did not put in the update, the problem is still there. I am running Nuendo 32, and my OS is Windows 7 64X. Other specs below.
