Solved BukkitGui Wont work

Please Help me, I tried to copy and paste a big chunk of land and that crashed my server, so I shut down my server and loaded my backup, When I tried to start the backup it said that there is already a server running on this port, and it suggested that I restart my computer so I did. and when I tried to load my bukkitgui all that it displays is the settings and an error message shows up that says,

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Please help me, I spent a lot of time on this server
I also just switched ports and have been using the localhost

 

Please help Me

 

@Godzillasmash!, let me tag the creator to this.

Try deleting your GUI config file. Depending on your settings it's either located in

• [your_bukkitgui_location]\Bukkitgui2\config\config.xml
• %appdata%\Bertware\Bukkitgui2\config\config.xml

If this doesn't work, you can try deleting the whole config folder.
Deleting the config folder, or config files, will only reset the GUI settings. Your server won't be affected. However, it is advised to still make a backup of everything before proceeding.

 

Thank you so much. you saved me a bunch of time And thanks for your time
