Save problems in Spearhead

I'm in the Ardenne (sp) forest level and can proceed from it's starting point , but can't save. My save screen indicates a saved location of say 13:00 but the file name doesn't change from Ardenne Forest. If I die or try to load the level, it starts me right back at the beginning of the Forest Level. Any help is appreciated. I'm gonna just continue to try to do the level without any saves. Yeah Right !!!
