For 2 days, the `Login button` is disabled, why?
Thank you for your message.
I recommend you to restart the TeamViewer service.
-Execute "run", type "services.msc" and press OK
-Now find TeamViewer, and restart it by doing a right click.
Then, restart the TeamViewer application. It should work again.
I hope this could help. If not, do not hesitate to contact us again.
