Groove Agent doesn't load kit from friend's songs

My friend is using Cubase Artist on a PC and I’m using Cubase Pro on MBP. We send songs to each other to work on separately.

When he sends me a song I can open it OK apart from Groove Agent doesn’t remember what kit he’s used, and I have to manually select the kit before it will make any sound. Not a massive problem, as long as I know which kit he’s used to create the song, but it is a little bit annoying.

Anyone else had this problem and/or know of a fix?
