Have a v2018 PU2 macro running fine for months; suddenly 2 view lines of code do not work

I get

run-time error '-2147467259 (80004005)'
Method 'OpenView' of object 'IAccpacDBLink' failed

here is the punch line

Public OEHdr As AccpacCOMAPI.AccpacView
Public OEDet1 As AccpacCOMAPI.AccpacView
Public OEDet2 As AccpacCOMAPI.AccpacView

    mDBLinkCmpRW.OpenView "OE0520", OEHdr
    mDBLinkCmpRW.OpenView "OE0500", OEDet1
    mDBLinkCmpRW.OpenView "OE0740", OEDet2

OEHdr and OEDet1 no longer work, OEDet2.... OEDet12 work fine

running macro under Sage 300 and NOT using  vbs works fine
