Prior to sp2 my camera and scanning wizard stopped working.

Not sure when but when I start up the app it reports that it cannot see my scanning device ( astraslim SE). If I use the Astra software its fine, If I uninstall the drivers and reinstall XP reports all ok. its just the scanning and camera wizard refuses to recognise that the Bl**dy thing is connected.
Ms knowledge base seems to have no info on this problem. I did read somewhere that Realplayer could be causing the problem but Ive removed this and nothing has changed.
Has anyone else had this problem recently and more importantly have they fixed it?
