Still not working :(. I tested the following: removed both Xee and The Unarchiver and installed Xee alone (to make sure Xee will definitely find nothing else). After the box you mentioned poped up I installed The Unarchiver and tried again - the box did not appear though Xee wasn't able to open the archives. However Console.app did not show any error message at all :(.

I'd like to give you some better failure descriptions, unfortunately I don't have Xcode/Objective C experience (I assume python knowledge doesn't help at this point... :( ).
