Hey there,
I have problems with my teamviewer 11. While version 10 is working perfectly, when I try to connect with teamviewer version 11, it says that there are problems with a protocol.
I have to use version 11, though, because this is the version I have bought a commercial license for.
As version 10 is working, I think I can assume that there can not be a problem with the router or windows firewall. What can I do to make it work?
Thanks in advance
