I still have trauma's of messages like 'A file error has occured'. I fear your scene might have been corrupted and that it is unable to retreive your scene. The 'unexpected end of file' part is new to me, usually it's just 'unexpected error occured'. You might want to try a memorymanager or more RAM to see if the scene just doesn't fit in your systems memory or if the file really is corrupted.
