Andrew,

Well, VB syntax sometimes throws me for a loop, but try setting up your View's Table when you first instantiate it, something like this:

Dim ExportFilesFinder As New DataView(ExportWorkingData.Tables("ExportFiles"))

Also, I noticed that you're setting two unnecessary properties ... unnecessary because you're setting them to the defaults anyway, so why bother:

.RowFilter = ""
.RowStateFilter = DataViewRowState.CurrentRows

Oh, I forgot to ask ... on which line are you getting the error?
