See WinSCP suddenly opens with two local panels with seemingly no option to open a connection to my server. What do I do?

Hi, I've recently changed things on WinSCP because my remote site is now using RSA encryption. In making changes I lost the right-hand panel and it's been replaced with a copy of the left hand local one. How do I get rid of this and replace it with something using only the following:

User name: xxx
Host name: xxx.xxx...edu.au
Port number: xxxxx

?
