Just made a few tests. Pauline 2 and Roxie are looking for missing texture files. In Pauline 2's case, the missing files originally were in the Pauline 1 texture folder - a folder that was deleted when installing Poser 11.2. I did not bother looking for the exact missing textures for Roxie. I had been paranoid enough to back up my old Poser 11.1 Runtime and copied my old texture folder into the new one. Everything is fine now.

Just checked the Legacy Content zip; Pauline 1's texture files, some of which Pauline 2 still needs, are missing from there. That zip needs an update; best check for all texture files.
