Our PDM Workgroup vault has had lost references for about 2 years.  We tried working with our reseller and with solidworks to resolve the problem, but found no solution.  When we find these problems we perform a Pack and Go from the "latest" directory and recheck them in with the same revision.

I recently found this fix for lost references in PDM Enterprise (https://forum.solidworks.com/message/120185).  Is there a fix similar to this for Workgroup that may solve our problem?
