the application looks "promising" but ... it doesn't work. support also doesn't respond. where should I look for instructions?

Switches you to paid version randomly, you have to downgrade it manually if it does.

I just uninstalled then reinstalled, not sure why it started me on paid when i only wanted free

Now random CSS is applied to it. I cant get it to work on free because of the mess ups made to it on paid. I didnt even want paid.
