Problem with Sculptris!

[fleasapprentice]

I worked on a sculpture of one of the people from Avatar for about 4 hours. I was saving it periodically. All of a sudden, it crashes. I opened it back up to open my saved copy from 15-20 minutes earlier, but it won't open. I keep getting the 'too many triangles connected to an edge' error. I never exported it and now that it won't open, I can't stick it into Blender or anything like that to fix it. It is saved still as an sc1. Does anyone know how I can fix this? I don't want to lose this sculpture as it is one of my best ever. This is the unfinished piece. This was taken like 30 minutes before it crashed. Tell me what you think so far...it's my first sculpture
