@leocg Thank you for the advice. It got me at least a partial success in that now I'm connecting with the free Opera VPN. The problem still remains, that my VPN Pro status on my Opera account is set to "inactive", despite a successful payment to NexWay. Somehow the communication between the NexWay and the Opera database seems to be inadequate.

After successful payment, my VPN Pro account is shown active with NexWay but inactive in the Opera account. I have followed the advice of login out and in again and even restartet the PC. To no avail. Please advise.
