Access 2003 and Word 2003 bug????

[_Carolyn]

I am doing a mail merge from Access and keep getting an error:
5852 Requested object is not available.

I did a search and found many people have this error and I dont see any
resolution. .Destination = wdSendToNewDocument 5852

Its Access 2003 calling Word 2003, in vba code.
It bombs out at -->.Destination = wdSendToNewDocument
Thank you,
Carolyn
