unable to run macro!

[dfuas]

Hi everyone,

I have a problem trying to run a Access 2003 WinFax application. These application was originally designed in Access 97 and I am trying to updated to Access 2003, but when I run it I get errors such as: error: -2147352573Unable to run specified macro and error:4198Command failed although it works well in the original Access 97.
The application querys a database and mail merges a document in word to be sent to fax machine.

Any help?

Thanks
