DZP  You're blocking the site referrer (last site visited). Turn off (momentarily) that option in whatever application (NetBarrier perhaps?) you are using and you won't get into a loop trying to download files hosted by MacUpdate. I presume MacUpdate does this to avoid hot-linking to files.

DZP  There was never a script to launch the iTunes-Lame application, it used to be that placing the application in the ~/Library/iTunes/Scripts/ folder, it would be accessible from iTunes' script menubar item and "just work". This has changed since a few iTunes releases. You can no longer (with the current iTunes version at least) access an .app directly from the script menu, but a simple workaround is to write your own script as follows :

- Open Script Editor ( /Applications/Applescript/Script Editor ).

- Paste the following line :

tell application "iTunes-LAME" to launch

- Save the script as "iTunes-LAME" with File Format: Script.

- Place your new script in ~/Library/iTunes/Scripts/ and it'll show up in the iTunes' script menubar item. Clicking it will launch the iTunes-LAME application.

Note that the iTunes-LAME application itself can be left in the /Scripts/ folder or you can place it in your /Applications/ folder. Now it "just works" again. ;-)
