Airfoil 4.9.2 breaking plugin?

Did an update and I'm getting this error:

Airfoil Error Update failed. Check to see if Airfoil is functioning correctly.

What version of Indigo and the Airfoil plugin are you using?

Also, make sure you have a source selected in Airfoil.

I think we are ok. I restarted the computer and was still getting an error. Then, I used Airfoil to send audio from Safari to some speakers, went back to Indigo and reloaded the plugin and it worked. Your suggestion of selecting the source may have been the problem. Thanks!

This bug was fixed in 6.0.21 (and later) along with other things so you might want to consider installing the latest version.
