Quote - I have the same problem. In addition I am running Poser on an external hard drive with a separate runtime for V4. Now I can't get elite morphs to work, but I remember having a big problem when I first got V4 which is working OK now. If you get elite to work let me know how you did it.

It seems to me that you can only use one set of morphs at a time, which I am sure is not how it's supposed to work.
I have the morphs++ installed and working and I have the Elite and Muscle morphs installed. 
Everytime I use the Muscle Morphs I get the same 'Please locate InjDelta.FBMBodyBuilding'.

So I can't use those morphs.

Elite works though.

What trouble are you having? 
BTW using an external HD should be no problem.
