hello after installing M4L on Win7, I need assistance to resolve a malfunction.

At the opening of "Navigation Tools API" or "Kapture" lessons

live.object / pet path:error calculating the path

I did nothing else than installing M4L ...

I understand even less this problem because when I open

this lessons on my Macbook M4L there is no such error.

I clear that I use an external hard drive on which I have my common ABLETON library

I clear that I use an external hard drive on which I have my common ABLETON library
between Win7 and Mac OS 10.5.
