Prtoteus, No need to reinstall anything. P5 allows you to acquire anything from your P4 runtime folder. In fact, I typically still install everything non-P5 specific in my P4 runtime and use the new folder system to retrieve it from there. (This allows me to still use them in P4 when I want to use it--typically to do speedy renders which don't need to be raytraced as P4 is less taxing on the system.) I hope this helps. --lb
