problem with Halion

Im having problems with halion.

I save a renoise song with a halion patch loaded.
Then when I try to load the song, renoise dont open the song with the halion patch loaded.

I supose that will be a problem of samples path (like the problem of Virtual Guitaris)

Anybody can help me? Its posible modify some strings on registry to avoid this problem?

Best regards.
