I'm updating links in Excel workbook from MS Access app.
It was working well and I didn't do any changes.
But, now I'm getting an error during the debugging:
"Error number 1004: Application-defined or object defined error."
Before that, I've got some error that links cannot be updated in
...._Workbook (but no this error message during the debugging).

Dim xlapp1 As New Excel.Application
Dim xlbook1 As New Excel.Workbook

xlapp1.DisplayAlerts = False
xlapp1.AskToUpdateLinks = False

Set xlbook1 = xlapp1.Workbooks.Open(strOurFileName, True)

With xlbook1
.UpdateLink Name:=.LinkSources ' Here is the error
End With

xlapp1.ActiveWorkbook.Save
xlapp1.Quit

Could anybody clarify how I could fix it?

Thanks
