windows explorer can't open files from vault

My pdm vault was updated 2 weeks ago. Since then I can no longer open vault files by using windows explorer. I can search for vault files, and see vault files I want to use by using windows explorer however, when I try to open them nothing happens.    ...or on a rear occasion, it will open in another instance of solidworks giving me that same old "journal file cannot be created" error msg.

Thoughts?
