The first problem is easy to solve, this is a general problem with the german poser (the developers who did such a nonsense of translating the names of library folders should be #&!%...): Don't rename "Posen", just make a new folder named "Pose" and copy all of the V3 morph injectors into this folder. If you select then something under "Posen/V3" the morph injector will be taken from "Pose". You can also edit the files for correct reference and only use your "Posen" folder but I think it's much easier to spend this additional 20 megabytes...
