Or, of course, use the library in the same, or higher, version of Max you created/refreshed it with. It's a Max thing (the non-backward compatibility), and the only way you have to ensure it won't happen again is by doing all the addition/conversion from the lower Max version you have available. ThanksThis is due to adding/refreshing materials with the script (under the 'Add to library' button), but doing so from a max version higher than the one you tried reading them from.
