Pardon me for jumping in here ....
I use VBA code to do this. I have found that it works better to first run a make table query using your saved query as the source and storing the data into a temp table. Then you can export the table.
You may be able to export from your saved queries directly.
CODE
' run the make table queries
CurrentDB.Execute "qryExport_1_MakeTable"
CurrentDB.Execute "qryExport_2_MakeTable"
CurrentDB.Execute "qryExport_3_MakeTable"
CurrentDB.Execute "qryExport_4_MakeTable"
' export the data from the tables
DoCmd.TransferText acExportDelim, , "tmpExportTable1", strPath & "\qryExportTable1.txt", True
DoCmd.TransferText acExportDelim, , "tmpExportTable2", strPath & "\qryExportTable2.txt", True
DoCmd.TransferText acExportDelim, , "tmpExportTable3", strPath & "\qryExportTable3.txt", True
DoCmd.TransferText acExportDelim, , "tmpExportTable4", strPath & "\qryExportTable4.txt", True
