[AccessD] "class not registered" error - revisited

After all my problems with using wizards for list box and combo boxes, and 
getting the "class not registered" error, I installed Access2003.

Now when using the wizard I get "Data cannot be retrieved from the source 
you have selected. You must select a different table or query to continue 
in the wizard."  I checked out Microsoft kbid=839783, and even updated all 
the updates.  Still no go.  Now I really think there must be something 
wrong with my Windows2000 op.

Perhaps someone has other insights.

Thanks
