Need help fixing a bug with this program...

Question

I've been working for hours trying to fix the bug I have with this program...
http://ss.majinnet.com/AccountManager.java - This is the source code of my program
http://ss.majinnet.com/Dalzhim.jpg - This is an image used inside the program
http://ss.majinnet.com/sphereaccu.scp - This is a text file you need to use the program
First of all, to know what bug I am talking about.. You will need to download those 3 files.. Then you can compile AccountManager.java and run it.. When the program has opened, go into: File -> Open Account File
and browse until you can open up the text file sphereaccu.scp ... Then there should be a list of names appearing on the left, and when you select any, there will be variables appearing in the TextFields on the right. When that's done, all you have to do to see where the bugs are is to use the options: Edit -> Create New Account as well as Edit -> Remove Account ... When you use the Create New Account option for the first time, it works fine.. But when you use it a second time, errors are appearing on the console (can't find what generates those errors...). And the biggest problem is that when you use the Remove Account option, it doesn't remove the selected account, and over that it generates errors in the console as well...
If anyone can help me fix those errors, I'd be very grateful !

won't pretend to understand everything or why you do somethings, but FWIW,
