Excel 2000: Changing path of an external data source

I built a pivot on data using the "External Data Source" function. The data is held in an Access table.

I have since moved the Access file and as such the path to which the Pivot table is pointing to has changed.

My issue is I cannot seem to be able to find a way to update the new path and hence I cannot refresh my pivot.

When i try point to the Access file in the new location I get the following errors.

The error reads "ODBC Microsoft Driver Login Failed"

The query cannot be edited by the Query Wizard. When you hit OK the next text box says '(file name)is not a valid path. Make sure the file name is spelt correctly and that you are connected to the server on which the file resides.'

Is it possile to somehow (simply) ammend the path name somewhere?

Any help greatly appreciated.

any suggestions?
