query wizard has stopped working how do i rectify this
 

I am using windows xp and since the change over from windows 2000 i am not
able to refresh queries from my database to excel. Is this a firewall
problem?
How do i get the wizard to work again and update information for this year?
It just isnt connecting to the new information that has been put in. My
database is a access database and queries which were set up before the
upgrade are still there but as soon as i go to refresh data everything is
blank.

Is this an activex problem if so how do i rectify it?
