[B19 Mac] XML errors at startup main menu

[Mystic]

Every time I start up the downloaded build 2009 for the Mac, I get the errors below shown in a dialog as soon as the main menu appears, before I have even tried to set up a game.  I have no mods installed ... this is the completely unmodified B19 Mac build as downloaded from SendOwl (not Steam).

Try to find and delete the Config (folder) and delete it.
Maybe these error's are from settings from the old Rimworld version.

Yes, that was it, thanks!  Sorry if this was an obvious/common error or anything ... I haven't tried to play RW for several versions until now.

Nah, it is more a mistake from the Dev, not to add a version check for the config's too.
