Deathstalker Ultimate not working in Windows 10

My Deathstalker Ultimate was working fine on Windows 8. But after an up-gradation to windows 10, it stopped working. Whats weird is, the keyboard lights up with the profile and apps also load on the switchblade, even synapse 2.0 shows the keyboard. But the neither the keys nor the switchblade(tactile keys and touchpad) are responding at all. Tried everything like, reboot, reinstall, uninstall then clean install, pressing esc+caps lock+space keys and connecting the two usbs; but nothing works. Anyone has any idea? Please help!!!!
