Question : ODBC Access Driver - Connection for viewing linked Excel worksheet lost AND "File Now Available" pop up

I have an Excel report - 6 worksheets. 1 that has cells to input a date range. MS Access is linked to these dates and uses them as criteria to run the database queries on the other 5 worksheets. I use a macro behind a button to save the workbook and refresh the queries. Sometimes (in the morning) it works fine. Other times, it gives me the ODBC error message above. Attached is a screen shot of the ODBC Data Source set up. The Macro code is below. I added the wait time hoping that would help...

May or may not be related but often, when I close it, for no apparent reason, it will re-open with a "File Now Available" window saying that it is now available for Read-Write editing. When it was open previously, it WAS exclusive, not Read Only.
