"Audio Engine does not report back to Synfire Pro" error

I have recently try to update from Synfire Pro 1.7.13b4 to latest 1.7.16 build #4 for Mac OS and on two different systems I get different errors:
 

1. Yosemite 10.10.2 - while running Little Snitch I get the "Audio Engine does not report back to Synfire Pro" error (see attachment) and the app almost freezes or becomes very unresponsive. With Little Snitch turned off it loads fine, though.  I made new rules with Little Snitch allowing ingoing and outgoign connections with ip 127.0.0.1 port 8822 but with the same result ( workstation ip is set to 127.0.01 witin the audio engine , too (64 bit).  I have turned off the Little Snitch, in order to start working, opened cubase pro 8.5.20, loaded the cognitone drone, opened Synfire pro, but when trying to click "add drone" button, cubase unexpectedly quits.

I went back to 1.7.15 version and everything works fine after restart. But when trying to load libraries within the arrangement window ( by clicking on the book symbol) if the libraries list is too long, they won't scroll.

But 1.7.16 still crashes cubase when adding a drone.

2. Mountain Lion - the second system - no problem with Little Snitch (it's an older version, though), but after installing the latest 1.7.16 build #4, Cubase Pro 8.5.20 opens up and crashes after 20-30 seconds, just after it loads the plugins.

Installed 1.7.15 - everything is ok so far.

Any thoughts on how could I deal with the "Audio Engine does not report back to Synfire Pro" error on Yosemite?

Thank you in advance! It is such a useful software, I don't insist on having the latest version  installed, but want to figure out what could be wrong with my setup.

This could point to an incomplete install that left parts of the previous version installed. A re-install should fix it. With the next update, an improved uninstaller app will do better work in removing all parts completely before a re-install. If you do it with the current uninstaller app, your recently opened files history will be lost (not a biggie, but just be warned).

Little Snitch would usually not block the loopback interface (127.0.0.1). Maybe your settings are too strict?

I remember there has been a discussion about Cubase 8 crashes and the Audio Engine on the forum. Did not find it yet, though. Only thing I remember is they got it fixed ;-)

Andre, thank you so much for taking your time to write back so fast. Will search for myself for that Cubase related discussion on the forum, too. After adding the ingoing and outgoing rules on little snitch and restart, all things are working just fine with 1.7.15, except that when trying to open my libraries from arrangement window (by clicking the book icon), the scroll is not working, so I can only select first 30 libraries or so (it depends on the screen resolution) - as explain in the previous post. Is there a quick fix for this issue? As far as I remember, with version 1.7.13 scrolling was working.

Also, on my Mountain Lion install (laptop), after installing version 1.7.16 all of my DAWs crashed, including Logic and Ableton, not only Cubase. On my deskop Mountain Lion system (the backup/editing station), only Cubase crashed (Logic worked fine, but I don't have ableton installed on that one). So went back to 1.7.15 with all of them :)

I'll wait for the latest update, then.

P.S.: Did I mentioned that I really, really love Synfire? :) I can't recommend it enough and I keep telling people to give it a try .

Thanks for the positive feedback. Much appreciated.

Other DAWs crashing after a Synfire install points to a ReWire issue. Either the ReWire library or Synfire's Transport module for ReWire don't match, or the ReWire library is corrupted. 

Synfire does not replace the ReWire library, if it is newer than that included with our installer.  You'll find all shared ReWire stuff in /Library/Application Support/Propellerhead Software. Maybe move the ReWire bundle aside and let Synfire install its own and see if it helps. 

Be sure you make a backup before deleting anything.

Many applications using the same 3rd party shared code (ReWire) often leads to issues.
