Two guesses as to what the problem is:
(1) The file is corrupt
OR
(2) While Photoshop 1.0 is an old app, the Stuffit archive might have been created by someone more recently, using Stuffit 5 or later. Stuffit 4 will not open some .sit files created with later versions of Stuffit.
Try Googling - or searching other threads here - for links to Stuffit Expander 5 (or Aladdin Expander 5, as it's also called). It's the last version that will run on 68k Macs, and it is usually able to open all .sit files.
Good luck!
