Creo Illustrate File Losing Step Sequences

I built 2 pretty massive files for a presentation to our corporate group. The 1st one took 4 days, and was complete, but once saved, and reopened, all of the steps were gone. While I put in a ticket with PTC, it might be faster to try to find an answer here. I recreated the entire file, saved along the was, 6backups, and Published. While I kept them open, both files were perfect. Closed, reopened, BAM, all the steps were gone, but the last step I had highlighted is now the only Figure remaining. Open the pvz file, and them sBOM and views for each Step are screwed up. Is there a step number limit that kills it? I think I had 79 steps.Any help. please? This presentation was to get approval and funding to implement a global assembly and service documentation system, and Illustrate was it, but not for long if I can't fix this.
