TeamViewer 7 appeared ID missing error

Hello there,
After I finished to work with TeamViewer 7 this error appeared and I don’t know what ID is missing. When I want to connect with another PC this error appear again. How do I fix this? Also the reinstall of TeamViewer is not working and please tell me what is causing this error message?
Thanks!
