Would you please elaborate a bit more on what you're seeing. Are you having troubles liveSyncing to a connected device or using the 3-finger gesture. If you have connected an iOS device running iOS 8.3 please note that we currently have a known issue with the liveSync of those devices. This issue is already addressed and a fix will be available with the upcoming release.
If the iOS version is not the cause for the issue, please zip the contents of the %localappdata%\Telerik\BlackDragon\Logs
folder and send them over. Thank you in advance for the cooperation.
