Help Kies Air will will not load on sgs2 (middle of scanning)

[mystvearn]

I am not sure if updated kies air from the samsung market but when I tried to turn it on today, I see the normal scanning files, then the green bar disappears and all I get is the word "Scan". When I tilt the hp at different angle I do see the green bar again but it stop midway. Nothing else happens. Anyone know how to fix this?

Thanks
