I found a very easy and simple way to join my server and for others to join. Goto toparkservers.com
Enter your server name in the search box, wait for it to list if running, follow directions to run game. Runs the client thur Steam. Works great for me.
OK, it seems that IE was timing out and not allowing the control panel to refresh. I installed Firefox, and the control panel now works fine. Thankyou support for responding so quickly with a solution to my problem.
