I tried connecting to my friend's computer today. He tells me the code every day he wants me to help out with something, Today I tried connecting to him by double clicking his computer from the Team Viewer desktop app. Nothing happened, I didn't get the popup window asking for the password, so I clicked a few more times.
After this, the application told me that 'Due to too many failed attempts I'm blocked from connecting to the device for 3872731 seconds' (roughly 45 days).
So I'm blocked without even trying to enter a password, and I have no Idea what to do.
