I have been setting up a sandbox vault to make sure everything is exactly what we want before we start using PDM.  I'm at the point I want to start setting up our final vault but I am unable to open it up in explorer.  I can open my sandbox vault, and view the files no problem, but when I click on the new vault, Windows Explorer crashes.  I am the only one with this problem.  Other users can view both vaults without any issues. I've logged in with my personal account and the admin account as well, and it crashes for both.

Does anyone know what could be causing this?
