CAN'T PLAY SHOCKWAVE MOVIE EVEN IN ROSETTA MODE

I'm having trouble playing a shockwave movie even after downloading the latest version of shockwave player and setting safari in rosetta mode. I keep having this message: "DIRECTOR PLAYER ERROR. The application requires an Xtra (text) that either doesn't exist or failed to initialize properly. Please make sure the appropriate Xtras are in the Xtras folder(s)". I thought everything was supposed to run fine when safari is set in rosetta mode. Could anyone help cause I don't know what else to do? Thanks.
