Can't establish Secureline VPN

Suddenly I can’t get a Secureline VPN connection on my PC.

My license is current.

I tried changing my VPN location, but that didn’t work.

I tried going to the area where I could uninstall, but it asks for a password.

AFAIK the only one I have is the one that Avast assigned with my license, and it won’t work. I tried every variation of a common password I use, but none will work.

Anyone have any advice?

You have the builtin version of SecureLine. Right?
If yes, try to disable SecureLine component and install the standalone version:
