Have seen the same error her, but however have not a replicated vault.
Too correct this I RMB the file and choose history see who was the latest user that checked this file in. If that user open the file in SolidWorks then Check out and then check in again everything works for us.
Thank you!!! We've experienced this issue twice in the past few days and this made a quick and easy fix!
...If [the user that last checked in] the file in SolidWorks then [checks it out] and then [checks it] in again...
