Editing this post, I finally got it.....disregard my question below. At least I think I got it. We'll see.
In the attachment below I found out what messed me up.
In version 4, is the saved sequence saved as a .fseq file?
I was thinking it was saved a .xseq, but I could not find it in the show directory. so I opened a .fseq in the show directory to convert to .vir.
There are 5 models in the sequence, 1 Mtree and 4 arches. In another post I was told that all the models in the sequence would be converted at the same time. At the time I was writing this I couldn't find that post or I would have added this post to it. But I later found it in the Export Model thread.
However, when I choose to convert the .fseq file to a .vir file I am directed to select individual models. The option to convert all at the same time is not available. What am I not doing right?
