VB error running WinXP-Pro-Gold Edition

I've installed WinXP-Pro & installed as well Office 2000 with all the patches available on the Microsoft web .
What ever I start/or close(word, excel,pwp,etc...) I have this error message:
Microsoft visual basic compile error in hidden module:autoexec....
The version is : 9.0.44.02 SR-1 (Office)

But i can work normally .
I've uninstall office, restart my computer & install again office, still have the same pb.

Thanks
