Can't Change Servers

I’m not able to change the servers in TC.
Not sure if this is because I’m using the free version.

For ‘Advanced Options’ the ‘Automatically select best server’ is selected and all the other options are grayed out.
(See attached image for a screenshot.)

Thanks for the input!

It’s a limitation of Free TrustConnect version.
