I have been using Teamviewer for ages without any problem. It had rock solid stability until now.
Now I have 14.1.9025. on my win10 PC and nothing works 
I can start the aplication and it logs in. That's OK. Whenever my partner starts Teamviewer on the remote computer it appears as active on my side and problem starts.
- My Teamviewer disconnects then logs in again in every few seconds.
- I cannot connect to the remote computer, neither with password nor with remote approval.
- Meanwhile Teamviewer app simply closes sporadically.
- If I able to connect somehow (one out of 20 trials) teamviewer initiates a second session in the background within some seconds. At least I can see a message that it cannot connect as there is already one active session. At the same time I loose the mouse control on the remote computer. I can see the screen but cannot do anything
I sent some feedback within the app but have not got any feedback. Please help!
Full reinstall did not help.
