I'm not really sure what exactly Renegades does. I believe it may replace files which have also been replaced by later modifications to Outpost 2, so there is the potential for version issues, but I'm not familiar with what exactly changes. Maybe check the link you use to open Outpost 2 for any /loadmod parameters. There is more than one way to load a mod, and the NetFix used to use the /loadmod parameter.
