If I try to unstuff with Stuffit and get the message:

The Stuffit version I am using is 4.0.1.

This is the file I am trying to expand.

Any idea of what is going on? Google did not help on this very much... :'(

Thanks for a quick reply...

Edit: there is another Photoshop 1.0. version that I am trying to uncompress. Stuffit 4.0.1 yields the same error.

The file is this.
