John, thanks for the tips. I tried them all and nothing worked. BUT.....

I tried again this morning and for some reason I can now get MultRiffs to work fine, but not sure yet about generation of RealTracks.
I will have to investigate further, but I would like to thank all for their help and suggestions so far.

Will report back later.
