Unable to connect to any server

[cmnd-vennie]

Hi, I installed eOVPN, and loaded the configuration file. However, in "settings" I cannot add a username or password. When I go back to the main screen, the list of IP Addresses are shown, but it seems that I cannot click on the "Connect" button, or the button does not respond, when I click on it.
Any ideas?

The OS is:
