Yes lies is one crap software & personally will Mott go anywhere it.. Can be unstable as many (thousands) of have experienced firmware update crashes, leading to soft bricked phones..
Have you got the mtp application in your phone, this allows connection to kies.. Also on some occasions kies software does not recognize rooted phones..
Try to uninstall it & reinstall, our try using an older version..
What is it you want to do, using the lies software..??
