There are 2 variants of the .xml files (in the ui folder) - depending on... we're not sure... But with the invention of the logic to remove Content Paradise we became aware that some xml files were different. And these directly influence what's loaded and in what order. First thought was that either the very early versions were some how different, or that the patch path was different, depending if you went SR1, SR2<"betas">, SR2, etc., or straight to SR. Given that CL is reportedly suggesting re-install and patch to SR3 or 4 directly to some, this might suggest that the issue is with SR2... But this is all hypothesis. As Poser is clearly very buggy, it's of course not possible to predict behaviour, as repeatability just isn't ever there in buggy apps.
