Advanced support has let me know that the issue has been resolved for you. I'm glad to hear your system is operating normally again.
If this should ever happen in the future, there are a few things you could try to resolve it without calling and waiting for a fix.
1) The My Account app (version 1.15) now offers the ability to reset your touchscreen. The app is available for both iOS and Android devices.
2) Performing a hard reset with the pin hole on the back of the touchscreen.
3) If your alarm is not armed, you can disconnect the power cable from the touchscreen and disconnect the battery from underneath the kickstand.
