I upgraded to Lion last week and have been unable to get Switch to work since. I'm attempting to convert a FLAC file to MP3 for instance (my most common usage of Switch) and receive the following errors:
"You can't open the application mp3el because PowerPC applications are no longer supported."
and
"You can't open the application flacdec because PowerPC applications are no longer supported."
Anyone have a workaround? I emailed Switch support about this issue but have heard no response. It seems that Lion essentially bricks the app.
