“Bad format” alert when trying to authorize or download Rack Extensions

If it’s Reason that launches when you try to authorize, or download rack Extensions, the “phrem” protocol is wrongly associated with Reason as the helper app. The “phrem” protocol should instead be associated with┬áthe Authorizer application.

  • If you are using Firefox as your web brower, simply go to Preferences/Applications and verify that “phrem” is handled by Authorizer.
