Strange problem with Lion and Starcraft2

Hi, just installed Lion - yesterday, all worked fine, SC2 ran without any problems, now i run SC2 from dock - icon bumps, spot showing that app is running appears and disappears and thats all, no error, no starcraft, what the heck is happening???

 

eh

reinstall? i just installed it yesterday btw, sc2 map editor works just fine... any hint what may be wrong with that?

 

Update

it does not start if launched from dock or launchpad, but if I browse to application folders and run it there, it works... any idea how to fix it?
