I am not sure what your problem might be, but I have had RDS files which would not open after importing Poser 4 figures. I would think importing files from Poser 3 should work OK. I have imported many Poser 3 files without too many problems. I know you can import Poser 3 or 4 figures into RDS as OBJs, but you lose the features you have using the Poser importer. Make sure you have the last Poser Importer, too. I think it was version 2.7. If all else fails, the bones program for RDS from AFX.com might help animate an OBJ. Just some things to try. Beth
