I would agree 100% do not use public trackers. Too risky, as you just saw. However, your VSP should be encrypted anyway. But none the less. I use NordVPN and openVPN for everything.

To configure your VPN with your VSP, you should check with your support for that VSP. Sorry to say it, but each VSP is different and they typically have a lot of documentation for those things. If worse comes to worse, depending on your VSP provider, a good duck duck go/google search might have what you need.

Best of luck, I apologize if this wasn't much help.
