Despite multiple resets (soft, hard, factory), the same problem keeps occuring. I'm trying to configure an Airport Express N (1st Gen). Should be easy enough, but when I open Airport Utility, despite being able to see the AE, I constantly get Error 4. If I try "File ... Configure Other ..." etc., I get Error 6753. I have run out of ideas. Any help would be appreciated. PS: I tried this via wireless link, ethernet link - in every case, Utility sees the AE, but errors-out before the Config window appears. Thx in advance for your help.
