Useless

Teamviewer 12 is now useless. Needs a restart of Teamviewer on the remote computer each day(authentication rejected error), which isn't always possible... 
Other times, logging on, it hangs in the GUI and gives NO way to do anything.. Both computers are new, the internet is not an issue, and other applications works well even remote.

Also rebooting doesn't work either. Teamviewer tells me the computer is available, it's just stuck on initializing display.
