Hi all,for the last 2 or 3 days I've not been able to access the Dell support centre , it looks like it's going to load but then gives me the following error message -  'content for this program is not yet available. Please close the program and check again later'.  The program won't respond from the Notification Tray so I have to run from the programs list but I keep getting the above error. I've uninstalled and reinstalled but still the same result. I'm using dimension 3100 running XP. Any advise would be gratefully received. Thanks.
