I have the same problem as outlined in the article here:
https://community.teamviewer.com/t5/TeamViewer-12/Error-You-established-and-aborted-connections-too-frequently/td-p/5562
When opening TeamViewer, I had a pad of paper resting on my right-hand "enter" key without knowing it. This caused TV to go into a mental connect/abort.cycle. Now, TV refuses to work at all, claiming I have tried too many times.
Can you PLEASE change this "security protection" to something more realistic? I cycled probably 10 times... that's nothing compared to an actual DoS attack. Not to mention the stupid UI fault allowing this to happen.
When your UI and "security features" inhibit the use of your product, you have failed at designing your product. Please try again.
