Since a recent upgrade to Office 2003 (as well as a concurrent change to my
excel data document), when I open my main merge document, I get the following
messages:
1. Opening this doc wil run the following SQL command: SELECT from "active
Sites$". Data from your DB will be place in the doc. Do you want to
continue? Yes No. This part is fine. But upon selecting YES, this error
message:
2. This operation cannot be completed because of dialog or database engine
failures. Please try again later. After clicking OK ...
3. I have to "Find data source" ... ...
I have to do this for each and every merge document since this particular
excel spreadsheet is the data source for all my merges.

Thanks for your help.
