Compare Project Versions error '1101'

[Saulius Simkonis]

I am using Project Professional 2003. I am constantly getting the same errors
when trying to compare project versions.

First error:
- Title: Compare Project Versions Utility
- Message: Run-time error '1101'. The argument value is not valid.
- OK

Then second error:
- Title: Error!
- Message: An error occurred in the COM Add-in named: Compare Project
Versions. Error #:440. Automation error. Please restart Microsoft Office
Project to restart the COM Add-in.

I am getting these errors in the same sequence all the time. When I working
with project localy and when connected to the Project Server. On my own
computer and on my colleque PC. With different Project files containing just
few sample tasks.
I have never succeeded in my attempt to run this Compare Project Versions
utility.

Could anybody suggest me any ideas?
Brgds, Saulius

I see similar error has been fixed in SP1.
I have installed SP1 but this doesn't help.
