The Obj files for Rex and Roxie are in CU1 update.  If you go to the bottom of the page for updating Poser you will find two buttons that allow you to download the updated content (Mac/Win).

Please read the file that comes with it since the CR2 is overwritten and if you wish to keep using V1.0 of the figures you need to make a backup copy of them.

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13
