[X4U] Stuffit Deluxe 8.02 upgrade/.sit problems

[Samantha Cornell]

Has anyone successfully upgraded from Stuffit Deluxe 8.0 to 8.02?  I 
downloaded the updater, but it just installed another copy of 8.0...not 
what I wanted.

Also, I am trying to open a .sit file, and keep on getting an error 
#-40.  Is there a way around this?  Is there another app that I can try 
to use to unstuff it?

Thanks for your help!
