I have been using TextMate (licensed) for several years. A few days ago, I did the most recent update. Now, TextMate will not launch at all. I get a dialog box telling me TextMate is not supported on this architecture. But I have NOT upgraded to Snow Leopard, so I can't figure out why it is happening. I'm still running Leopard, version 10.5.8. Does anybody know what's wrong and how I can fix it? 

I seem to recall a discussion about how an upgrade could sometimes lead to incorrect permissions inside the app bundle… Not sure about that though.

The easiest fix should be to download the latest release from macromates.com and just use that :-)

HTH,
