Xmage - Won't run after launching client

Hello,
I am not the most computer literate person so I am hoping I can get some help. Screenshot attached
I recently downloaded Java and Xmage. Everything was working great until I went to register my account. In the middle of registering the program froze. I received my email giving me the initial pre-set password that I needed to complete my registration. I restarted Xmage launcher and have received the following error (check screenshot).
I must have clicked the remember my login information because now it thinks I have already registered and tries to automatically log in.
This is a guess at best!
I am running macOS Catalina version 10.15.3
Thanks for the help.
