I just installed AutoShade 2.0 w/Renderman. AutoShade works well. All went well until…page 119 of the tutorial. When the Process Info Box came up, it showed: "S01001 No Message: can't open message file: /rman/messages\s.msg" and was followed by a similar message for the codes R10007,S01001 (this one was repeated 6 times), D01002, and at the end: "**Autodesk Renderman exited by fatal error**". I've tried other files with Renderman with the same results (Autoshade works fine). Any suggestions?
