Have BSIS on five computers (2yr 5 PC package)....have had a year long battle keeping my one Win 7 Pro 64bit system running with BDIS 2011 but seems to be running without issues now for a month or so. (no issues with Win 7 Pro 32bit PC)
However...now my Win XP Pro 32bit system will not update for over a week now. Tried all the tricks I used to get the Win7 Pro system stalbe...but can not get the Win XP Pro system to update. Had been running reasonable well for over a year now...but now I get (for a week now) the following update error:

However...there is no alert for updates in the system tray...so I don't know if BDIS 2011 is updating despite the error message or not ?
I know there have been posts on this since I used to have the same issue with the Win7 Pro 64bit machine..but I haven't been able to find anything in my forum searches.
Have tried to repair/install and also download/update manually via weekly update but same problem ?
Any ideas on how to get this PC and BDIS 2011 to play nice together again ?
