Weird Error When Changing to Gen 7 Profiles

I Get this weird error report whenever I Load a gen 7 profile (specifically when I switch from gen 6 format to gen 7, and only the first time). I don't know what is causing it, or how to fix it. I think there might be something wrong with the config files, but I don't know where to look to find them. I also think this might be making it so my egg seed won't update when I select a profile, as I find whenever I switch to my gen 7 profile, the egg seed always goes back to the one i first entered when i made the profile, not the updated one i was using when i last used the profile.

This is the error report. Sorry if this doesn't count as an issue. I just couldn't figure this out and this seemed the best place to ask about it.

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:

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.
