If you go to System Preferences > Network > Advanced > Proxies, check and see if any boxes are ticked when Jaksta is closed. There should be none. When you open Jaksta, Web Proxy (HTTP) and Secure Web Proxy (HTTPS) should be turned on. Once you close Jaksta, they should turn off again. Does this happen for you, or do you experience something else?
A relatively big part of the update is addressing some of the proxy issues that people have been having, so if there's going to be a simple fix then I'd say that is your best bet.
While it is a paid upgrade, if Jaksta still does not work for you then we would offer a full refund for both the cost of the upgrade and your original purchase.
These proxy issues are often the hardest type of problem to fix, and sometimes it just comes down to the setup of the Mac that cannot be troubleshooted no matter how much you try. But if you don't want to update your OS or upgrade Jaksta, then we will try and fix it as it is.
