K-Relay Microsoft .NET Framework problem (common issue?)

(didn't used to happen) whenever I open Krelay now, it loads 4 [GameData] things, then gives me that error ^^ (removed link)

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.


Any ideas/solutions? It happens on both computers I've tried it on, but it didn't used to happen.

Also, what's the "upload system" I checked the rules and I'm 99% sure this isn't breaking the rules, but what even is the upload system?
